Character profile sanitization improvements (#25579)

Validate that job and antag prototypes can actually be set in character profiles, rather than just checking if the prototype exists.

Make preferences system just call existing validation code when loading prototype from database, instead of some hacked-together stuff.

Also I made the character profile validation logic take dependencies in via parameter because fuck resolves.
