Wire schema v1 into a manual Supabase migration and vendor the real stack
- Move db/schema.sql to supabase/migrations/ as the first supabase CLI
  migration (manual `db push` only, no automated runner); re-add the
  gebos_ingest role + grants there since init.sql never re-runs
- Add gebos-postgres-passwords oneshot on db-host: syncs role passwords
  from sops (LoadCredential, journal-safe), makes supabase_admin
  SUPERUSER and hands the auth schema to supabase_auth_admin to match
  the upstream supabase/postgres image; add pg_hba rule for 10.0.0.0/8
- Vendor the official docker-compose (studio/kong/auth/rest/meta only,
  external Postgres, loopback Studio with no Kong dashboard route) plus
  kong.yml (trimmed) and kong-entrypoint.sh (verbatim); tested: compose
  config, Kong config parse, migration applied on TimescaleDB pg17
- Document decisions as ADRs 0001-0004 (migrations, passwords, vendored
  stack, JWT API keys incl. verify/mint procedure)
