Add confirmation system to prevent pfUI from using evaluation-only tracking

Problem: Macro conditional evaluations create tracking entries, but
pfUI's AddEffect can fire during these evaluations (before actual cast),
causing it to use incorrect combo point data.

Flow before fix:
1. Macro evaluates [combo:>0] → TrackComboPointCast(0 CP, confirmed=false)
2. Macro evaluates again → TrackComboPointCast(1 CP, confirmed=false)
3. pfUI AddEffect fires → uses tracking (wrong timing!) ✗
4. SPELLCAST_START fires (actual cast)

Flow after fix:
1. Macro evaluates [combo:>0] → TrackComboPointCast(0 CP, confirmed=false)
2. Macro evaluates again → TrackComboPointCast(1 CP, confirmed=false)
3. SPELLCAST_START fires → sets confirmed=true ✓
4. pfUI AddEffect fires → only uses tracking if confirmed=true ✓

Changes:
- Added 'confirmed' field to tracking (default: false)
- SPELLCAST_START sets confirmed=true when spell actually casts
- pfUI AddEffect hook only uses tracking if confirmed=true
- Clear confirmed flag after use to prevent reuse
- Clear on failed/interrupted casts

Debug shows: "Ignoring X tracking (not confirmed - evaluation only)"
when preventing use of evaluation-only data.
