CoA's 3.3.5 client returns spellId as the 11th UnitAura value (stock 3.3.5a
stops at 10). The scan loop now captures it and the whitelist/blacklist match
on name OR spellId. The filter 'add' box accepts a numeric spell ID (stored as
a numeric key so it matches UnitAura's spellId) and the list view resolves IDs
to 'Name (ID)' via GetSpellInfo. Fixes ambiguity from name-only matching where
CoA custom spells share display names across ranks/variants.
