Fix combo point tracking for spellbook and action bar casts

The CastSpell and UseAction hooks were only confirming existing
tracking, not actually creating it. They also called the original
functions before capturing combo points, so the points were already
consumed.

Changes to CastSpell hook (spellbook casts):
- Get spell name BEFORE calling original CastSpell
- Capture combo points to lastComboPoints if spell is combo scaling
- Call original to cast the spell
- Call TrackComboPointCast to track the combo points used
- Confirm the tracking

Changes to UseAction hook (action bar casts):
- Get spell name from action slot BEFORE calling original UseAction
- Fixed tooltip logic (was checking "not GetActionText" incorrectly)
- Capture combo points to lastComboPoints if spell is combo scaling
- Call original to execute the action
- Call TrackComboPointCast to track the combo points used
- Confirm the tracking

Both hooks now capture combo points at the exact moment before the
spell is cast, ensuring they're available in lastComboPoints for
TrackComboPointCast to use as a fallback.

This fixes tracking for:
- Clicking spells from spellbook (CastSpell)
- Clicking spells on action bars (UseAction)
- Keybinding spells on action bars (UseAction)
