feat(filters): match aura whitelist/blacklist by spell ID, not just name

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.
