Fix what an independent review of the published repo turned up

- CI pinned Node 20, but `node --test` with type stripping needs 22.6, so the
  workflow could never have gone green. CI and `engines` now say 22.6.
- `docker compose up -d` failed on the documented path: the compose files
  require DB_PASSWORD and .env.example never mentioned it. Documented, and the
  README no longer claims "three secrets".
- The secret scanner treated any comment line as safe, so a pasted `.env`
  fragment — the usual way a key gets committed — slipped through. Verified
  against planted keys before and after.
- Module pages were not guarded: with KLARBILD_MODULES=print a signed-in user
  could still open /shares, /library and /queue and read about features the
  instance does not have. They now redirect, matching the API's 404 behaviour.
- German left in the English build: `bild.<ext>` as a download fallback, and
  31 t() keys with no German at all — the whole main navigation among them, so
  a German instance rendered its nav in English. Dictionary now covers every
  key in the source (1,067 entries).
- Third-party names removed from the data as well as the labels: the `theframe`
  format id is now `tv169`, and the dead Cricut admin field is gone.
- Dockerfile ignored the committed lockfile; it now copies it and uses `npm ci`.
- Dropped an unused dependency (@aws-sdk/s3-request-presigner — storage.ts
  explains why presigned URLs are not needed), a dead `/g/` entry in the
  unauthenticated path list, and an undocumented N8N_WEBHOOK_URL that nothing
  read. Documented TRUSTED_PROXIES, which the rate limiter does read.
- Migration 004 still had "nas" in its filename; README said A6–A2 where the
  list runs A6–A1; two committed screenshots were referenced nowhere.

124 tests green, type check clean, build clean, secret scan clean.
