Fixes#11832
This lets the user see more options than the three that appear
in the typeahead menu, and prevents them from inputting invalid
stream names.
This change replaces the input field with the dropdown, and
updates everything that referred to the classnames of the old
input field, so that they now get the data they need from the
new dropdown.
When in a private narrow, the "Message X" button is disabled if direct
messages are not allowed in the organisation and the current recipient
is not a bot.
Note that when the recipient is a user group with 1, more or all bots,
the button is disabled then too as such PMs are not allowed. Only when
the recipient is a single bot, then it's not disabled, as DMs with one
bot are allowed even in organisations where DMs are disabled.
Updates frontend user-facing strings with "private message" or "PM" to
use "direct message" or "DM" respectively instead.
Note that this updates translated strings as well as a few that
are not translated like search suggestions.
Updates `tools/lib/capitalization.py` for some specific strings
that are impacted by these changes, and removes "PM" and "PMs"
from checked strings.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
