Fix debuff conditionals using wrong max duration for combo spells

CRITICAL FIX: Debuff conditionals like [debuff:Rip<4] were using base
duration (12s) instead of actual combo duration (28s for 5 CP).

**Problem:**
- SeedUnit rescans debuffs on target change/UNIT_AURA events
- It called lib:GetDuration(spellID) without combo awareness
- This overwrote combo-aware durations with base durations
- pfUI cooldown module showed wrong max duration (12s vs 28s)
- Conditional [debuff:Rip<4] triggered at wrong times

**Solution:**
1. Updated lib:GetDuration to accept optional comboPoints parameter
2. Checks CleveRoids_ComboDurations[spellID][cp] FIRST before other sources
3. Priority: combo learned > caster learned > static database
4. SeedUnit now uses highest learned CP duration as fallback
5. When rescanning combo spells, assumes 5 CP if learned

**Benefits:**
- [debuff:Rip<4] now uses actual 28s max duration (5 CP)
- pfUI cooldown displays correct duration
- Conditionals trigger at correct times
- Prevents base duration from overwriting learned duration

**Example:**
Cast Rip with 5 CP (28s), macro refreshes at <4s remaining (24s used)
Previously: Would refresh at <4s of 12s base (8s used) - TOO EARLY!
