feat(studio): expand nitro cleanup with repair, auto-clean, and orphaned assets
CI / check (push) Successful in 4m15s
CI / preflight (push) Skipped
CI / deploy (push) Successful in 1m59s

Scan distinguishes fake, broken, and orphaned SWF/icon assets with age
metadata, deletes per asset kind, re-downloads broken nitro bundles from
configured sources, auto-cleans old fake leftovers, and exports a JSON
manifest. Adds rebuild and auto-clean API endpoints with audit coverage
and a housekeeping preview route under the hotel domain.

Verified: full vitest suite (2213 tests), typecheck, and biome all pass.
