27e924c7cd fix(auth): remove synthetic-admin bypass (Brief 2 of fix-auth-bypass)
Closes AGENTS.md gotcha #2: getUserFromRequest no longer returns a
hardcoded { userId: 1, email: 'admin@tcgvault.com', role: 'admin' }
when the Authorization header is missing or malformed.

lib/permission-middleware.js
  - getUserFromRequest now returns null for missing/malformed Bearer
    headers. No console.warn, no NODE_ENV gate — the fallback is gone,
    period.
  - Token-verify path and DB lookup unchanged.

pages/api/auth/verify.js
  - No-token branch now returns 401 instead of fetching the seed admin
    via `WHERE email = 'admin@tcgvault.com'`. Closes the admin-record-
    leak side of the same bypass.
  - JWT-verify branch unchanged.

Known follow-up (flagged but NOT addressed in this PR):
  pages/api/collections/[identifier]/cards.js POST/PUT/DELETE handlers
  dereference user.userId without a null guard. Previously masked by
  the synthetic admin (anonymous-write-as-admin on collections owned
  by user 1 was the security hole). Now degrades to NPE → 500 instead
  of a clean 401. Security is improved either way; cosmetic 500-vs-401
  fix lives in a separate one-line follow-up PR.
