Aman Agrawal ac8d5a5f0b remote_billing_page: Show error page for registration mismatch.
When a self-hosted Zulip server does a data export and then import
process into a different hosting environment (i.e. not sharing the
RemoteZulipServer with the original, we'll have various things that
fail where we look up the RemoteRealm by UUID and find it but the
RemoteZulipServer it is associated with is the wrong one.

Right now, we ask user to contact support via an error page but
might develop UI to help user do the migration directly.

Mateusz Mandera ec7245d4e1 remote_billing: Add redirect flow for users with expired session.
Implements a nice redirect flow to give a good UX for users attempting
to access a remote billing page with an expired RemoteRealm session e.g.
/realm/some-uuid/sponsorship - perhaps through their browser
history or just their session expired while they were doing things in
this billing system.

The logic has a few pieces:
1. get_remote_realm_from_session, if the user doesn't have a
   identity_dict will raise RemoteBillingAuthenticationError.
2. If the user has an identity_dict, but it's expired, then
   get_identity_dict_from_session inside of get_remote_realm_from_session
   will raise RemoteBillingIdentityExpiredError.
3. The decorator authenticated_remote_realm_management_endpoint
   catches that exception and uses some general logic, described in more
   detail in the comments in the code, to figure out the right URL to
   redirect them to. Something like:
   https://theirserver.example.com/self-hosted-billing/?next_page=...
   where the next_page param is determined based on parsing request.path
   to see what kind of endpoint they're trying to access.
4. The remote_server_billing_entry endpoint is tweaked to also send
   its uri scheme to the bouncer, so that the bouncer can know whether
   to do the redirect on http or https.

Prakhar Pratyush 49388d5d3d topic_mentions: Fix restriction rule for @-topic mentions.
Now, the topic wildcard mention follows the following
rules:
* If the topic has less than 15 participants , anyone
can use @ topic mentions.
* For more than 15, the org setting 'wildcard_mention_policy'
determines who can use @ topic mentions.

Earlier, topic wildcard mentions followed the same restriction
as stream wildcard mentions, which was incorrect.

Fixes part of #27700.

Alex Vandiver 5ee4b642ad views: Add a /health healthcheck endpoint.
This endpoint verifies that the services that Zulip needs to function
are running, and Django can talk to them.  It is designed to be used
as a readiness probe[^1] for Zulip, either by Kubernetes, or some other
reverse-proxy load-balancer in front of Zulip.  Because of this, it
limits access to only localhost and the IP addresses of configured
reverse proxies.

Tests are limited because we cannot stop running services (which would
impact other concurrent tests) and there would be extremely limited
utility to mocking the very specific methods we're calling to raising
the exceptions that we're looking for.

Zixuan James Li f4caf9dd79 api: Add new typed_endpoint decorators.
The goal of typed_endpoint is to replicate most features supported by
has_request_variables, and to improve on top of it. There are some
unresolved issues that we don't plan to work on currently. For example,
typed_endpoint does not support ignored_parameters_supported for 400
responses, and it does not run validators on path-only arguments.

Unlike has_request_variables, typed_endpoint supports error handling by
processing validation errors from Pydantic.

Most features supported by has_request_variables are supported by
typed_endpoint in various ways.

To define a function, use a syntax like this with Annotated if there is
any metadata you want to associate with a parameter, do note that
parameters that are not keyword-only are ignored from the request:
```
@typed_endpoint
def view(
    request: HttpRequest,
    user_profile: UserProfile,
    *,
    foo: Annotated[int, ApiParamConfig(path_only=True)],
    bar: Json[int],
    other: Annotated[
        Json[int],
        ApiParamConfig(
            whence="lorem",
            documentation_status=NTENTIONALLY_UNDOCUMENTED
        )
    ] = 10,
) -> HttpResponse:
    ....
```

There are also some shorthands for the commonly used annotated types,
which are encouraged when applicable for better readability and less
typing:
```
WebhookPayload = Annotated[Json[T], ApiParamConfig(argument_type_is_body=True)]
PathOnly = Annotated[T, ApiParamConfig(path_only=True)]
```

Then the view function above can be rewritten as:
```
@typed_endpoint
def view(
    request: HttpRequest,
    user_profile: UserProfile,
    *,
    foo: PathOnly[int],
    bar: Json[int],
    other: Annotated[
        Json[int],
        ApiParamConfig(
            whence="lorem",
            documentation_status=INTENTIONALLY_UNDOCUMENTED
        )
    ] = 10,
) -> HttpResponse:
    ....
```

There are some intentional restrictions:
- A single parameter cannot have more than one ApiParamConfig
- Path-only parameters cannot have default values
- argument_type_is_body is incompatible with whence
- Arguments of name "request", "user_profile", "args", and "kwargs" and
  etc. are ignored by typed_endpoint.
- positional-only arguments are not supported by typed_endpoint. Only
  keyword-only parameters are expected to be parsed from the request.
- Pydantic's strict mode is always enabled, because we don't want to
  coerce input parsed from JSON into other types unnecessarily.
- Using strict mode all the time also means that we should always use
  Json[int] instead of int, because it is only possible for the request
  to have data of type str, and a type annotation of int will always
  reject such data.

typed_endpoint's handling of ignored_parameters_unsupported is mostly
identical to that of has_request_variables.

Zixuan James Li 84723654c8 webhooks: Use 200 status code for unknown events.
Because the third party might not be expecting a 400 from our
webhooks, we now instead use 200 status code for unknown events,
while sending back the error to Sentry. Because it is no longer an error
response, the response type should now be "success".

Fixes #24721.

Eeshan Garg 2393342e03 webhooks/jira: Handle anomalous payloads properly.
We recently ran into a payload in production that didn't contain
an event type at all. A payload where we can't figure out the event
type is quite rare. Instead of letting these payloads run amok, we
should raise a more informative exception for such unusual payloads.
If we encounter too many of these, then we can choose to conduct a
deeper investigation on a case-by-case basis.

With some changes by Tim Abbott.

m-e-l-u-h-a-n aea31eb31f api: Add REALM_DEACTIVATED error code.
In `validate_account_and_subdomain` we check
if user's realm is not deactivated. In case
of failure of this check, we raise our standard
JsonableError. While this works well in most
cases but it creates difficulties in handling
of users with deactivated realms for non-browser
clients.

So we register a new REALM_DEACTIVATED error
code so that clients can distinguish if error
is because of deactivated account. Following
these changes `validate_account_and_subdomain`
raises RealmDeactivatedError if user's realm
is deactivated.

This error is also documented in
`/api/rest-error-handling`.

Testing: I have mostly relied on automated
backend tests to test this.

Fixes #17763.

sahil839 37c8505435 message: Raise exception when trying to mirror an already sent message.
Previously we were just returning a dict containing a message id when
trying to mirror a already sent message in 'zephyr_mirror' cases.

This commit changes this behaviour to raise an exception when trying
to mirror an already sent message by adding a new exception class
ZephyrMessageAlreadySentException and then the caller returns the
message_id directly, instead of calling do_send_messages which also
returns a list of size one containing the message_id only.

This is a prep commit for changing the return type of check_message to
be a dataclass instead of a Dict as now we have only single output for
check_message.

Any exception is an "unexpected event", which means talking about

this is about an _unsupported_ event type.

This also switches the path that these exceptions are written to,
