This commit adds code to add "(guest)" to user names of guest
users in the following places -
- right sidebar
- user pills, including the pills in search suggestion typehaead
- typeaheads for user
- sender names in message feed
- user profile popover and modals.
- user name in not subscribed warning banner.
Note that the indicator is shown only if enable_guest_user_indicator
setting is set to true.
As a result of this change, we now translate "deactivated" text
shown in user pills for deactivated users.
Fixes part of #26700.
Remove bootstrap-tooltip class `popover-title` from code.
It was only used in user_card_popover for showing user avatar,
so cleaned up properties that were duplicated or not required.
