Assemble QMS app + SQLite refactor + Unraid single-container deploy

Reconstruct the full app from init-source overlays (base + fix-1..6 +
update-1..3, last-wins) at the repo root, complete the missing pieces so it
builds and runs, and stage the Unraid deployment.

App completion:
- types/index.ts: former Prisma enums as string-literal unions + AppUser
- pages/_app.tsx + styles/globals.css (mount AppProvider/ToastProvider)
- API routes: auth/login, auth/me, users, submissions (+REVIEW_READY notify),
  forms (list/create), notifications
- scripts/create-admin.js: idempotent first-admin bootstrap
- 14 unbuilt nav targets stubbed via ComingSoon placeholder

SQLite refactor (single-container, no external DB):
- schema provider -> sqlite; enums -> String; Json -> String;
  FormField.options String[] -> JSON-encoded String
- lib/forms.ts (de)serialises options at the DB boundary
- drop mode:"insensitive" (unsupported on SQLite)
- enum imports repointed from @prisma/client to @/types

Deploy:
- multi-stage Dockerfile (next build -> prod runner), docker-entrypoint.sh
  (prisma db push -> create-admin -> next start), .dockerignore
- docker-compose.yml: br0 10.2.0.x, /mnt/user/appdata/qms -> /data volume
- README rewritten for the Unraid/Gitea Actions flow; .env scrubbed of the
  live Supabase credential; vercel.json removed

Verified: next build clean (41 routes); live SQLite round-trip of
login/session, form options array, and submission -> REVIEW_READY.
