Add filters, stats bar, and fix bugs

- FilterBar: type chips (Monster/Spell/Trap), owned-only toggle, sort by name/most-owned
- Stats bar: cards in DB, unique owned, total copies
- Card detail panel: type, race, attribute, level/link stars from existing data
- useMemo for filtered+sorted card list (was re-sorting every render)
- Footer: refresh card list after successful full import
- PrintingRow: remove broken custom memo comparator (was comparing static DB field)
