Earlier, a 'large @-mention notification' warning that pops up
for stream wildcard mentions was shown for topic wildcard mentions
too, which is incorrect.
This commit fixes the incorrect behavior. We no longer show the
banner for @-topic mentions.
We don't need a banner for @-topic mentions, as those are much less
likely to be used without thinking about it and would rarely be spammy
for a lot of people.
Fixes#27767.
The function considers @**all**, @**everyone**, @**stream**,
and @**topic** as wildcard mentions.
Earlier, the function didn't have a check to match @**topic**
in the message_content.
Following the issue #23380 and PR #25038, this commit changes all
occurences of `uri` into `url` in all comments, local variables,
handlebars templates (.hbs) function names and their callers in
all `.js` and `.ts` files.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
