feat(d37): society category (Kerala co-op directory taxonomy) on clients

Adds client.category (SQLite migrate + PG migration 014), derived from the name to match
the official Kerala co-op classification: Service Bank / Urban Bank / Vanitha / Housing /
Employees / Agricultural / Marketing / Society (other) / Store / Other. Backfilled by a
portable CASE (most-specific-first); new/edited clients derive it via categoryFromName.
Clients screen gains a Category filter dropdown + column. Live backfill: 135 Service
Bank, 38 Employees, 15 Vanitha, 14 Store, 12 Agricultural, 11 Urban, … typecheck + full
suite (416) green.
