fix: Normalize USERS table timestamps before dm:save to prevent PostgreSQL type errors

- Add format-timestamp-for-postgres and normalize-user-timestamps functions in database.lisp
- data-model-save now normalizes timestamp fields for USERS table before saving
- Fix authenticate-user to use data-model-save instead of dm:save directly
- Add global auth state in auth-ui.lisp for other scripts to check login status
- Add auth checks in front-page.lisp and stream-player.lisp to skip API calls when not logged in
- Fix ParenScript parentheses structure in stream-player.lisp DOMContentLoaded handler

Fixes password reset, role update, and last-login update failures caused by
integer timestamps being sent to PostgreSQL TIMESTAMP columns.
