MiliUI Damage Meters

New
- Added a "MiliUI style" icon set: 40 hand-drawn specialization icons. It is now the default under Bars > Icon > Icon style. If you were using the old default (Specialization icon), you are switched to the new style automatically. Any other choice you made is kept.
- The hover preview and the breakdown view now open with a portrait card that shows a large spec icon, the player's name, their specialization and class, and their item level. Group members' item level comes from inspecting them, so it fills in outside of combat.

Fixes
- With a larger font size, the hover preview and breakdown header no longer overflow or overlap. Their height now follows the font size.
- In choice pop-ups, long translated button labels no longer spill onto the next button. Buttons now widen to fit the longest label.
- The main list no longer shows through the breakdown view.
