CRITICAL: Add confirmation to DoCast hook

The issue: None of the CastSpellByName/CastSpell hooks were firing because
CleveRoid macros go through DoCast, not the standard casting functions.

Evidence from user output:
- Many "ComboTrack: Rip cast with 5 CP" messages ✓ (TrackComboPointCast called)
- NO "[Confirmed]" messages ✗ (no hooks firing)
- "[pfUI AddEffect Hook] Ignoring Rip tracking (not confirmed)" ✗ (never confirmed)

The DoCast integration was calling TrackComboPointCast but NOT setting
confirmed=true, so pfUI would always see unconfirmed tracking data.

Fix: Add confirmation in DoCast hook, just like all the other cast hooks.

Now when user casts via CleveRoid macros:
1. DoCast fires → TrackComboPointCast → confirmed=true ✓
2. pfUI AddEffect fires → sees confirmed=true → uses duration ✓
