refactor(authz): use bun models in migration 099, wire oss role get

- migration 099 follows the migration-local row struct pattern: bun
  NewSelect/NewUpdate for the role table reads and backfill writes; the
  openfga store and tuple lookups stay raw like 081/083
- oss provider Get reads the role from the store instead of returning
  unsupported
