Alex Vandiver 8c72959951 push_notifications: Handle empty rendered_messages.
This parallels fe25517295, but for mobile notifications.  It also
adds a test, which verifies that such content does not crash either
mobile or email notifications.

Anders Kaseorg 9399b95fec push_notifications: Remove redundant APNs retry loop.
aioapns already has a retry loop.  By default it retries forever on
ConnectionError and ConnectionClosed, so our own retry loop would
never be reached.  Remove our retry loop, and configure aioapns to
retry APNS_MAX_RETRIES times on ConnectionError like the previous
version did.  It still retries forever on ConnectionClosed; that’s not
configurable but probably fine.

Alex Vandiver 094f22e6b4 notifications: Add safeties to prevent incorrect notifications.
de04f0ad67 changed now notifications recipients were calculated, in
a manner that caused them to be sent when they should not have been.
ac70a2d2e1 was supposed to resolve this, but appears to have been
insufficient, as all three of these cases have been observed to still
happen.

Add safety checks immediately before notification, until the
underlying logic error can be sussed out.

Sahil Batra 4c290a49d3 user_groups: Do not allow editing system user groups from API.
We do not allow any user to edit the system user groups (including
renaming, deleting, adding or removing members, etc.) from the
API. These user groups will change only by the code when a new
user is added or role of a user is changed.

This is implemented by rejecting access_user_group_by_id always
except the case when it is use to get the user group for sending
email and push notifications, as we would need to send notifications
to the mentioned user group.

Abhijeet Prasad Bodas de04f0ad67 notifications: Calculate PMs/mentions settings like other settings.
Previously, we checked for the `enable_offline_email_notifications` and
`enable_offline_push_notifications` settings (which determine whether the
user will receive notifications for PMs and mentions) just before sending
notifications. This has a few problem:

1. We do not have access to all the user settings in the notification
handlers (`handle_missedmessage_emails` and `handle_push_notifications`),
and therefore, we cannot correctly determine whether the notification should
be sent. Checks like the following which existed previously, will, for
example, incorrectly not send notifications even when stream email
notifications are enabled-
```
if not receives_offline_email_notifications(user_profile):
    return
```
With this commit, we simply do not enqueue notifications if the "offline"
settings are disabled, which fixes that bug.

Additionally, this also fixes a bug with the "online push notifications"
feature, which was, if someone were to:
* turn off notifications for PMs and mentions (`enable_offline_push_notifications`)
* turn on stream push notifications (`enable_stream_push_notifications`)
* turn on "online push" (`enable_online_push_notifications`)

then, they would still receive notifications for PMs when online.
This isn't how the "online push enabled" feature is supposed to work;
it should only act as a wrapper around the other notification settings.

The buggy code was this in `handle_push_notifications`:
```
if not (
    receives_offline_push_notifications(user_profile)
    or receives_online_push_notifications(user_profile)
):
    return

    // send notifications
```

This commit removes that code, and extends our `notification_data.py` logic
to cover this case, along with tests.

2. The name for these settings is slightly misleading. They essentially
talk about "what to send notifications for" (PMs and mentions), and not
"when to send notifications" (offline). This commit improves this condition
by restricting the use of this term only to the database field, and using
clearer names everywhere else. This distinction will be important to have
non-confusing code when we implement multiple options for notifications
in the future as dropdown (never/when offline/when offline or online, etc).

3. We should ideally re-check all notification settings just before the
notifications are sent. This is especially important for email notifications,
which may be sent after a long time after the message was sent. We will
in the future add code to thoroughly re-check settings before sending
notifications in a clean manner, but temporarily not re-checking isn't
a terrible scenario either.

Abhijeet Prasad Bodas c3319a5231 notification_data: Create common source for trigger strings.
This reduces loose strings in the codebase, and allows us to not worry
about the exact naming (`stream_email_enabled` or `stream_emails_enabled`?)
and tense (`mentioned` or `mention`?).

Ideally this new class should have been in `lib/notification_data.py`,
which is our file for things like this. But, the next commit requires
using this data in `models.py`, and importing from `notification_data.py`
to `models.py` causes recursive imports.

Alex Vandiver 0b7cff2f22 push_notifications: Hide "error" level messages from aioapns.
Work around Fatal1ty/aioapns#15, by silencing error-level logging from

send_notification calls by examining the `result.description` and
handling them; the extra logging message merely clutters the Sentry
logs.

Abhijeet Prasad Bodas 4d24499317 android notifications: Differentiate personal vs wildcard mentions.
The code to also notify for wildcard mentions was added in
0ed0bb6828.

But that showed the same text for both the cases. This commit fixes
that.

This is more of change for correctness. The mobile app currently does
not rely on this text for notifications, but constructs the text by
itself from the data in the payload.

This also fixes the "stream_push_notify" case to consistently show
a `#` before the stream name.

Tim Abbott 0be35f530b push_notifications: Replace 'REDACTED' string.
The previous string was bold, potentially confusing, and doesn't

similar setting enabled.

Shelly c958a023fe i18n: Add i18n to 'REDACTED' message in push notifications.
When a user has disabled message content in mobile push notifications,
we send a fixed string (currently "REDACTED") as the content of the
notification. Previously, this string was not tagged for translation;
we fix that here.

Additionally, because mobile push notifications are generated in a
queue worker, they do not have the user's language set by the Django
middleware. Our email notifications solve that problem using
`override_language`; we do the same here.

We choose to do override_language in get_message_payload_apns and
get_message_payload_gcm, rather than the caller, in order to be
consistent with tests.

Tested end-to-end by tabbott by setting a translation for "REDACTED"
manually in German.

Fixes #18713.

Hashir Sarwar ab6be2a711 push_notifications: Store tokens locally even when bouncer is used.
This makes the system store and track PushDeviceToken objects on
the local Zulip server when using the push notifications bouncer
and includes tests for this.

This is something we need to implement end-to-end encryption for
push notifications. We'll add the encryption key as an additional
property on the local PushDeviceToken object.

It also likely adds some value in the case that a server were to
switch between using the bouncer service and sending notifications
directly, though in practice that's unlikely to happen.
