Randall Stillwell 4a10dcedd3 fix(auth): centralize JWT secret + 24h TTL (Brief 1 of fix-auth-bypass)
- New `lib/auth-secret.js` is the single source of truth for `JWT_SECRET`
  and the canonical `JWT_TOKEN_TTL = '24h'`. Module throws at import time
  if `process.env.JWT_SECRET` is unset — no silent fallback to the literal
  `'your-secret-key-change-in-production'`.

- 7 callers refactored to import from the helper:
    lib/permission-middleware.js
    pages/api/auth-utils.js   (also drops unused `'7d'` → JWT_TOKEN_TTL)
    pages/api/auth/login.js   (also routes via auth-utils.generateToken)
    pages/api/auth/register.js (same)
    pages/api/auth/verify.js  (Brief 2 still owns the no-token admin branch)
    pages/api/favorites.js
    pages/api/users/search.js

- `process.env.JWT_SECRET` now appears exactly once in the JS source
  (lib/auth-secret.js). `your-secret-key-change-in-production` is gone.

- TTL drift reconciled: auth-utils used `'7d'`, login/register used
  inline `'24h'`. Both now route through imported `JWT_TOKEN_TTL` (24h).

Pre-deploy reminder: Vercel must have `JWT_SECRET` set before merge or
serverless functions refuse to boot. Existing tokens (signed against the
fallback literal) will be invalidated — users will need to log in again.

Resolves AGENTS.md gotcha #3. Brief 2/3/4/5 still pending in convoy.
