Full production-ready docker-compose stack (db, kong, auth, rest,
realtime, storage, imgproxy, meta, functions, studio) targeting
api.caterium.ru, plus bootstrap script for a fresh Cloud Server,
Caddy reverse-proxy config (HTTPS, WebSocket, upload limits), and
dump/restore/verify/storage-sync scripts for moving off the managed
Supabase project (cksuehzcimitsxmeloes). Does not touch public/ or
any live runtime behavior — frontend cutover is documented separately
in frontend-cutover.md and only applied after Etap 8 verification.
