Add override notice on Classes tab, include class in profile names

- Show "These settings are currently overridden" and grey out the
  frame checkboxes on the Classes tab, but only while viewing the
  logged-in character's own class and its active profile has the
  override enabled - other classes stay fully editable.
- GetCharacterKey() now embeds the class token ("Name - Class -
  Realm"), so auto-created per-character profiles carry it too.
  Migrate existing "Name - Realm" profiles/assignments/overrides to
  the new key on the affected character's next login.
