Improve UI layout, spell casting, and realm selection screen

- Fix action bar, bag bar, chat window to track window resize (Always pos)
- Show spell names in cast bar instead of spell IDs
- Play precast/cast-complete sounds via SpellSoundManager
- Fix hearthstone to use CMSG_CAST_SPELL directly (avoids slot sync issues)
- Show map name instead of coordinates in hearthstone tooltip
- Show cooldown time remaining in action bar tooltips
- Search equipped slots and bags for action bar item icons
- Redesign realm screen: back button, larger table/buttons, auto-select
  realm with characters, double-click to enter, proportional columns
