This commit includes other various improvements to watched words.
auto_silence_first_post_regex site setting was removed because it overlapped
with 'require approval' watched words.
The user summary's delete button UX relied on the "admin-user.js" destroy function, which was called through the "admin-tools" service. After #11724, we no longer put UX behavior on Ember models.
Admins can now edit translations in different languages without having to change their locale. We display a warning when there's a fallback language set.
A while ago we made a change to display a warning after installing a theme component when the admin tries to leave the page without adding the new installed component to any themes (see 5e29ae3ef5).
However there is an edge case that we forgot to address, and that's when an admin installs a component and then immediately opens the install modal again to install another one which can result in the warning being shown twice at the same time.
This PR prevents that by showing the warning when opening the install modal if the conditions are met (new component and not added to any themes) instead of showing it after installing the second component.
This makes it much easier to check the staff action logs for a specific site setting. A small history icon will appear when hovering over a site setting name. On click, you will be taken to the pre-filtered staff action log for the site setting.
Users could be silenced or suspended by two staff members at the same time and
would not be aware of it. This commit shows an error message if another penalty
has been applied.
