🆕 Token login added

Backend (AuthHttpHandler):
- New users_remember_tokens table stores sha256 hex of the raw token
  so the DB never holds a usable credential. Seed file adds the table
  and a login.remember.duration.days setting (default 30).
- /api/auth/login accepts "remember": true. On success, issues a fresh
  32-byte base64url token, stores the hash, returns the raw token.
- New POST /api/auth/remember: accepts the raw token, looks up by hash,
  on a valid hit mints a fresh SSO ticket, rotates the token (deletes
  the consumed one and issues a new one), returns both to the client.
  No Turnstile - it's an automated trusted-device flow.
- /api/auth/logout also accepts rememberToken and deletes that single
  row so other devices keep their tokens.

Frontend:
- LoginView: "Remember me" checkbox (key login.remember_me already in
  ExternalTexts). Enabling it persists the returned rememberToken in
  localStorage.nitro.remember.token.
- App.tsx: before deciding to show the login screen, try a silent POST
  to /api/auth/remember with the stored token. On 200, inject the
  returned ssoTicket into window.NitroConfig and proceed to the
  authenticated flow; on 401, forget the token and show login.
- PurseView logout: sends the stored rememberToken in the body so the
  server can delete it, and clears localStorage before reload.
