This commit adds new API endpoint to get stream email which is
used by the web-app as well to get the email when a user tries
to open the stream email modal.
The stream email is returned only to the users who have access
to it. Specifically for private streams only subscribed users
have access to its email. And for public streams, all non-guest
users and only subscribed guests have access to its email.
All users can access email of web-public streams.
This commit moves `maybe_get_stream_name` function from `stream_data` to `sub_store`
as it didn't had any dependency on `stream_data` and it also helps us to cut off
dependency on `stream_data` for some of the modules including `user_topics`.
Prior this commit, changing the message type from a stream (where posting
was not allowed) to a direct message using the compose box dropdown, did not
changed the state of the send button from disabled to enabled even though
direct messages were allowed in the organization.
This was happening because `check_stream_posting_policy_for_compose_box` was
only for streams.
Now, function is updated to check for both streams and direct
messages, as it checks if direct messages are allowed or not, and depending on
that, it updates the send button's state, tooltip and displays a relevant banner.
This also fixes the color on these icons in the stream-specific rows
of the notification settings table.

This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
