Replaces the stateless signed-cookie session (bare user_id) with a real server-side sessions table -- the cookie now just carries an opaque session id, resolved against the DB on every request. Each session records IP address (respects X-Forwarded-For), a parsed device label, and last-seen time (throttled updates, not written on every request). New GET/DELETE /api/auth/sessions endpoints and an "Active sessions" section in Profile settings let a user see every device they're logged in from and revoke one they don't recognize -- including their own current session, which just signs them out.
