Refactor announcements. (#19459)

* Refactor announcements.

* Actually make this a unit test

* Dumb

* Remove unnecessary 'as text'

* Reviews:

- Make CSS class a recognizable word
- Flip the defaults for logging

Also:

- Style fixes (default null in fields)
- Fix emergency/crew-transfer shuttle announcement titles
