Alex Vandiver e3c976fed9 missed_messages: Include messages from topic which differ by case.
In Zulip, message topics are case-insensitive but case-preserving.
The `get_context_for_message` function erroneously did a
case-sensitive search, and thus only messages whose topic matched
exactly were pulled in as context.

Make the missed-message pipeline aware that message topics are not
case-sensitive.  This means that, when collapsing adjacent messages,
we merge messages with topic headers which are "different"; create a
separate explicit "grouping" to know which to collapse.

Josh Klar c15d066bf5 email-notifs: Use bracketed prefix to indicate a resolved topic.
Some email clients (notably, Gmail Web) support automatically threading
emails together if recipients and subjects match[1]. Manual testing
indicated that prefixing a subject with "[bracketed content]" does not
break this threading behavior, but the added checkmark in a resolved
topic's title does. Before sending an email notification, determine
whether the topic is resolved, and pass this information to the Jinja
template to properly format a threadable email subject.

Fixes: #22538

Josh Klar 69c042bff6 email-notifs: Concatenate topic subject lines only in Jinja.
Previously, stream names and topics (without consideration for their
resolution status) were concatenated in Python-land and passed through
to the template. To more cleanly separate concerns, and to prepare for
accounting for topic resolution status being a third, independent,
component of a subject line, instead pass stream and topic strings
independently to the Jinja template, which can format them as it sees
fit.

sahil839 decc8d41fa emails: Add quote prefix ">" in plain text missed message emails.
We add quote prefix ">" to each line of the message in the plain text
missed message emails, which are then rendered as quotes by email
clients. We also move the message content in the next line after sender.

This helps us in clearly showing the message authors in missed message
emails especially in emails with multiple messages and senders.

Stop using `access_user_group_by_id` in notifications codepaths, as it
is meant to be used to check for _write_ access, not read
access (which is not limited).  In the notification codepaths, there
are no ACLs to apply, and the ID is known-good; just load it
directly. The `for_mention` flag is removed, as it was not used in the
mention codepaths at all, only the notification ones.

Abhijeet Prasad Bodas 15e8717847 notifications: Don't enqueue notifications for bots.
This replaces the temporary (and testless) fix in
24b1439e93 with a more permanent
fix.

Instead of checking if the user is a bot just before
sending the notifications, we now just don't enqueue
notifications for bots. This is done by sending a list
of bot IDs to the event_queue code, just like other
lists which are used for creating NotificationData objects.

Alex Vandiver 039b869ca5 email_notifications: Fix inline-ing of image-URL-only messages.
fe25517295 adjusted the email_notifications codepath to use
`lxml.html.fragment_fromstring` method when parsing
`rendered_content`, but left the tests using a helper which called
`fromstring`.

Switching the tests to match the code as run reveals a bug -- using
`drop_tree` on all `message_inline_image` classes now _does_ remove
all of a top-level image-URL-only message.  Previously, such messages
were "safe" from the block that calls `drop_tree` only by dint of
`drop_tree` being a silent no-op for the root element.  When parsed
using `fragment_fromstring`, they are no longer the root, and as such
an empty message results.

Reorder relative_to_full_url to check for only one `message_inline_image`
within the top `<div>`, and only run the `drop_tree` path in the
alternate case.  Tests must be adjusted for their output now including
one more layer of `<div>`.

Alex Vandiver fe25517295 email_notifications: Handle empty rendered_messages.
The transforms called from `build_message_payload` use
`lxml.html.fromstring` to parse (and stringify, and re-parse) the HTML
generated by Markdown.  However, this function fails if it is passed
an empty document.  "empty" is broader than just the empty string; it
also includes any document made entirely out of control characters,
spaces, unpaired surrogates, U+FFFE, or U+FFFF, and so forth.  These
documents would fail to parse, and raise a ParserError.

Using `lxml.html.fragment_fromstring` handles these cases, but does by
wrapping the contents in a <div> every time it is called.  As such,
replacing each `fromstring` with `fragment_fromstring` would nest
another layer of `<div>`.

Instead of each of the helper functions re-parsing, modifying, and
stringifying the HTML, parse it once with `fragment_fromstring` and
pass around the parsed document to each helper, which modifies it
in-place.  This adds one outer `<div>`, requiring minor changes to
tests and the prepend-sender functions.

The modification to add the sender is left using BeautifulSoup, as
that sort of transform is much less readable, and more fiddly, in raw
lxml.

Partial fix for #19559.

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.

We create a mini-markdown parser here that strips away the fence content

Our handling of html emails is much better in comparison where we can
use lxml to parse the spoiler blocks.
