Prakhar Pratyush 118a7e8d9d zulip_updates: Send zulip updates based on zulip_update_*_level.
This commit adds a management command that will run regularly
as a cron job to send zulip updates to realms based on their
current and latest zulip_update_announcements_level.

For realms with:
* level = None: Send a group DM to admins notifying them about
this new feature & suggestion to set the stream accordingly.

* level = 0:
  * If stream is still not configured, wait for a week
    before setting their level to latest level. They will
    miss updates until their configure the stream.
  * If stream is configured, send updates.

* level > 0: Send one message/update per level & increase
  the level by 1 till the latest level.

Fixes #28604.

Prakhar Pratyush 336d46001c message_send: Add 'internal_prep_huddle_message' function.
This is a prep commit to extract out the logic to
create message from 'internal_send_huddle_message'
into a separate function 'internal_prep_huddle_message'.

We will use this new function to get the huddle message
without sending it immediately.

Prakhar Pratyush 23fc04577b message_send: Don't create savepoint in do_send_messages.
In general, we never want to use savepoints.

This prep commit adds savepoint=False in do_send_messages
as we don't want to just rollback to this savepoint and
proceed if we encounter any error while sending zulip updates
via cron.

Alex Vandiver 7b1feac06a CVE-2024-27286: Remove UserMessage rows for non-active Subscriptions.
A user who was no longer subscribed to a private stream kept their
UserMessage row for a message sent while they were in it; this is
expected.  However, they _also_ kept that row even if the message was
moved to a different private stream that they were also not subscribed
to.  This violates the invariant that users without subscriptions
never have UserMessage rows.

Alex Vandiver e964536139 CVE-2024-27286: Run usermessage modifications even for change_one.
This `if new_stream is not None` block was improperly indented,
causing it to only run if the propagation mode was not `change_one`.
Since the block controlled creation and deletion of UserMessage rows,
this led to messages being improperly still visible to members of the
old stream if they were being moved from public to private streams.
Clients also failed to receive `delete_message` events, so the
messages remained visible in their feeds until they reloaded the
application.

Mateusz Mandera da9e4e6e54 backends: Implementation of restricting certain backends by plan.
Only affects zulipchat, by being based on the BILLING_ENABLED setting.

The restricted backends in this commit are
- AzureAD - restricted to Standard plan
- SAML - restricted to Plus plan, although it was already practically
  restricted due to requiring server-side configuration to be done by us

This restriction is placed upon **enabling** a backend - so
organizations that already have a backend enabled, will continue to be
able to use it. This allows us to make exceptions and enable a backend
for an org manually via the shell, and to grandfather organizations into
keeping the backend they have been relying on.

sayyedarib 5c993f0479 direct_message: Allow DMs to bots and self regardless of policy.
Previously, in DM disabled org messaging to bot was not working when
starting new conversation and adding bot as recipient because of not
updating on recipient change. And secondly, self messaging was not
allowed.
This commit ensures that the DM to bot and self are allowed irrespective
of dm restrictions.

Alex Vandiver 22837fc1b4 message_edit: Carry the QuerySet through as much as possible.
Rather than pass around a list of message objects in-memory, we
instead keep the same constructed QuerySet which includes the later
propagated messages (if any), and use that same query to pick out
affected Attachment objects, rather than limiting to the set of ids.
This is not necessarily a win -- the list of message-ids *may* be very
long, and thus the query may be more concise, easier to send to
PostgreSQL, and faster for PostgreSQL to parse.  However, the list of
ids is almost certainly better-indexed.

After processing the move, the QuerySet must be re-defined as a search
of ids (and possibly a very long list of such), since there is no
other way which is guaranteed to correctly single out the moved
messages.  At this point, it is mostly equivalent to the list of
Message objects, and certainly takes no less memory.

Alex Vandiver 822131fef4 message: Add a bulk_access_stream_messages_query method.
This applies access restrictions in SQL, so that individual messages
do not need to be walked one-by-one.  It only functions for stream
messages.

Use of this method significantly speeds up checks if we moved "all
visible messages" in a topic, since we no longer need to walk every
remaining message in the old topic to determine that at least one was
visible to the user.  Similarly, it significantly speeds up merging
into existing topics, since it no longer must walk every message in
the new topic to determine if the user could see at least one.

Finally, it unlocks the ability to bulk-update only messages the user
has access to, in a single query (see subsequent commit).

Tim Abbott 9efce0b16c create_user: Fix initial unreads ignoring private streams.
This logic was apparently missed when we implemented private streams
with shared history; the correct check is to look at whether the user
can access message history in the stream, which used to be equivalent
to whether it's a private stream.

Mateusz Mandera 6dd6fc045f realm_settings: Improve authentication_methods param validation.
The endpoint was lacking validation that the authentication_methods dict
submitted by the user made sense. So e.g. it allowed submitting a
nonsense key like NoSuchBackend or modifying the realm's configured
authentication methods for a backend that's not enabled on the server,
which should not be allowed.

Both were ultimately harmless, because:
1. Submitting NoSuchBackend would luckily just trigger a KeyError inside
   the transaction.atomic() block in do_set_realm_authentication_methods
   so it would actually roll back the database changes it was trying to
   make. So this couldn't actually create some weird
   RealmAuthenticationMethod entries.
2. Silently enabling or disabling e.g. GitHub for a realm when GitHub
   isn't enabled on the server doesn't really change anything. And this
   action is only available to the realm's admins to begin with, so
   there's no attack vector here.

test_supported_backends_only_updated wasn't actually testing anything,
because the state it was asserting:
```
        self.assertFalse(github_auth_enabled(realm))
        self.assertTrue(dev_auth_enabled(realm))
        self.assertFalse(password_auth_enabled(realm))
```

matched the desired state submitted to the API...
```
        result = self.client_patch(
            "/json/realm",
            {
                "authentication_methods": orjson.dumps(
                    {"Email": False, "Dev": True, "GitHub": False}
                ).decode()
            },
        )
```

so we just replace it with a new test that tests the param validation.

Currently, we use *topic as the local variable name for
