Cooldown Manager Extended - CDMx

### Hotkey Detection Overhaul

**Fixed: Incorrect hotkeys on Paladin and other classes**
- Replaced unreliable `cooldownID` frame property with `GetBaseSpellID()` method
- Blizzard's cooldown manager uses internal frame pool identifiers that don't correspond to the actual displayed spell
- Should improve hotkey accuracy across all classes

**Fixed: Hotkeys not showing for abilities on bars 2-10**
- Proper slot-to-binding mapping for all action bars (MULTIACTIONBAR3BUTTON, etc.)

**Improved: Spell override detection for talent replacements**
- Added mapping for Templar's Verdict → Final Verdict (Paladin)

**Enhanced diagnostic commands**
- '/cdmxdump' shows identification method and full resolution chain
- '/cdmxframes' probes methods on frames for debugging
