Mateusz Mandera a23b077b79 CVE-2023-28623: Prevent unauthorized signup with ldap + external auth.
Since 74dd21c8fa in Zulip Server 2.1.0, if:
- ZulipLDAPAuthBackend and an external authentication backend (any aside
  of ZulipLDAPAuthBackend and EmailAuthBackend) are the only ones
  enabled in AUTHENTICATION_BACKENDS in /etc/zulip/settings.py
- The organization permissions don't require invitations to join

...then an attacker can create a new account in the organization with
an arbitrary email address in their control that's not in the
organization's LDAP directory.

The impact is limited to installations which have the specific
combination of authentication backends described above, in addition to
having the "Invitations are required for joining this organization
organization" permission disabled.

Lauryn Menard a5b527f321 onboarding: Specialize Welcome Bot message for education organizations.
Because education organizations and users have slightly specialized
use cases, we update the Welcome Bot message content sent to new
users and new organization owners for these types of organizations
to link to help center articles/guides geared toward these users
and organizations.

Also, updates the demo organization warning to only go to the new
demo organization owner because the 30 day deletion text is only
definitely accurate when the organization is created.

Fixes #21694.

Prakhar Pratyush c8a9c0ee04 realm_redirect: Redirect always to the login page with the next parameter.
Previously, entering an organization via 'accounts/go' with the
web-public stream enabled took the user to the web-public view
even if the user was not logged in.

Now, a user is always redirected to the 'login_page' with
the next parameter, if present.

The 'login_page' view is updated to redirect an authenticated
user based on the 'next' parameter instead of always redirecting
to 'realm.uri'.

Fixes #23344.

Sahil Batra afc5066e36 registration: Fix "Resend" link not working for realm creation.
The "Resend" link for realm creation was not working correctly
because it is implemented by basically submiting the registration
form again which results in resending the email but all the
required parameters were not passed to the form after recent
changes in the realm creation flow.

This commit fixes it by passing all the required parameters -
email, realm name, realm type and realm subdomain, when submitting
form again by clicking on the "resend" link.

Fixes #25249.

Mateusz Mandera ffa3aa8487 auth: Rewrite data model for tracking enabled auth backends.
So far, we've used the BitField .authentication_methods on Realm
for tracking which backends are enabled for an organization. This
however made it a pain to add new backends (requiring altering the
column and a migration - particularly troublesome if someone wanted to
create their own custom auth backend for their server).

Instead this will be tracked through the existence of the appropriate
rows in the RealmAuthenticationMethods table.

Lauryn Menard f391bfeec6 emails: Add new onboarding email with guide for organization type.
Adds a new welcome email, `onboarding_zulip_guide`, to be sent four
days after a new user registers with a Zulip organization if the
organization has specified a particular organization type that has
a guide in the corporate `/for/.../` pages. If there is no guide,
then no email is scheduled or sent.

The current `for/communities/` page is not very useful for users
who are not organization administrators, so these onboarding guide
emails are further restricted for those organization types to
only go to new users who are invited/registered as admins for the
organzation.

Adds two database queries for new user registrations: one to get
the organization's type and one to create the scheduled email.

Adds two email logs because the email is sent both to a new user
who registers with an existing organization and to the organization
owner when they register a new organization.

Lauryn Menard ffcdc13819 create-realm: Update notification message sent to admin realm.
When a new realm is created, a notification message is sent to
the realm configured as the settings.SYSTEM_BOT_REALM if there
is a "signups" stream that exists in that realm. This is used
for Zulip Cloud, but is an undocumented feature.

The topic of the message has been the subdomain of the new realm,
and the message content has been "Signups enabled" translated
into the default language of the new realm.

In order to make these messages more explicitly for Zulip Cloud,
the settings.CORPORATE_ENABLED is checked before sending these
messages.

To make these messages more useful, the topic for these
notifications is changed to be "new organizations". The content
of these messages is updated to have the new realm name (with a
link to the admin realm's activity support page for the realm),
subdomain (with a link to the realm), and organization type.

Lauryn Menard 213d0f4990 create-user: Remove notifications sent to admin realm.
Removes the notification message that was sent if a stream named
"signups" exists in the `settings.SYSTEM_BOT_REALM`. This was a
undocumented feature that would send a notification message when
a new user registered with a Zulip organization that was hosted
by an admin realm like Zulip Cloud.

This removes two database queries when a new user is created: one
to get the system bot realm and the other to get the notification
bot in said realm.

Note that there are still notification messages sent when a new
organization is registered with the admin realm if the "signups"
stream exists.

Sahil Batra 0ed5f76063 settings: Add backend code for using user email_address_visibility setting.
This commits update the code to use user-level email_address_visibility
setting instead of realm-level to set or update the value of UserProfile.email
field and to send the emails to clients.

Major changes are -

- UserProfile.email field is set while creating the user according to
RealmUserDefault.email_address_visbility.

- UserProfile.email field is updated according to change in the setting.

- 'email_address_visibility' is added to person objects in user add event
and in avatar change event.

- client_gravatar can be different for different users when computing
avatar_url for messages and user objects since email available to clients
is dependent on user-level setting.

- For bots, email_address_visibility is set to EVERYONE while creating
them irrespective of realm-default value.

- Test changes are basically setting user-level setting instead of realm
setting and modifying the checks accordingly.

Aman Agrawal 37431cf0b5 urls: Provide `email` as a GET parameter.
Since we want to use `accounts/new/send_confirm` to know how many
users actually register after visiting the register page, we
added it to Google Tag Manager, but GTM tracks every user
registration separately due <email> in the URL
making it harder to track.

To solve this, we want to pass <email> as a GET parameter which
can be easily filtered inside GTM using a RegEx and all the
registrations can be tracked as one.

Prakhar Pratyush 1a400b21e7 notifications: Fix missed message email notifications of welcome bot.
A missed message email notification, where the message is the welcome
message sent by the welcome bot on account creation, get sent when
the user somehow not focuses the browser tab during account creation.

No missed message email or push notifications should be sent for the
messages generated by the welcome bot.

'internal_send_private_message' accepts a parameter
'disable_external_notifications' and is set to 'True' when the sender
is 'welcome bot'.

A check is introduced in `trivially_should_not_notify`, not to notify
if `disable_external_notifications` is true.

TestCases are updated to include the `disable_external_notifications`
check in the early (False) return patterns of `is_push_notifiable` and
`is_email_notifiable`.

One query reduced for both `test_create_user_with_multiple_streams`
and `test_register`.
Reason: When welcome bot sends message after user creation
`do_send_messages` calls `get_active_presence_idle_user_ids`,
`user_ids` in `get_active_presence_idle_user_ids` remains empty if
`disable_external_notifications` is true because `is_notifiable` returns
false.
`get_active_presence_idle_user_ids` calls `filter_presence_idle_user_ids`
and since the `user_ids` is empty, the query inside the function doesn't
get executed.

MissedMessageHookTest updated.

`context_data` is only available on `SimpleTemplateResposne`, we can't
narrow `TestHttpResponse` to it because the latter is not in fact a
subtype of `HttpResponse`.

Differently, `redirect_chain` is an attribute that only appears on the
test response when the test client method is called with `follow=True`.
`TestHttpResponse` does not have that by defalut, either.

The occurence of these two cases are rare enough throughout the codebase
and we can't get around that without aggressively overloading the test client
or refactoring `_MonkeyPatchedWSGIResponse` in the upstream.

Zixuan James Li fe9ed2e69d settings: Make INVITATION_LINK_VALIDITY_MINUTES optional.
Type inference does not work when the default value of `REQ` is
non-optional while `ResultT` is optional. Mypy tries to unify
`json_validator` with `Validator[int]` in `invite_users_backend` instead
of the desired `Validator[Optional[int]]` because of the presence of the
default value `settings.INVITATION_LINK_VALIDITY_MINUTES`, which is
inferred to be an `int`. Mypy does not resort to a less specific type but
instead gives up early.

This issue applies to invite_users_backend and generate_multiuse_invite_backend
in zerver.views.invite.

There might be a way that we can add an overload to get around this, but
it's probably not worth the complexity until it comes up again more frequently.

We do in fact allow `invite_expires_in_minutes` to be `None` in places
like `do_invite_users`, `invite_users_backend`, etc, and we have
`settings.INVITATION_LINK_VALIDITY_MINUTES` as the default for them. So
it makes sense to allow having an optional value for this setting. And
since there isn't a way to independently set the value of this constant,
we move it to a different place.

This is a temporary fix that should be refactored when the bug is fixed.

Mateusz Mandera 39d8a81e51 registration: Tie PreregistrationUser to the original MultiUseInvite.
Fixes #21266.

We want to tie the prereg_user to the MultiUseInvite directly rather
than to the MultiUserInvite's confirmation object, because the latter is
not possible. This is because the flow is that after going through the
multiuse invite link, the PreregistrationUser is created together with a
Confirmation object, creating a confirmation link (via
create_confirmation_link) to which then the user is redirected to finish
account creation. This means that the PreregistrationUser is already
tied to a Confirmation, so that attribute is occupied.
