release: v0.5.0

## Summary

- **Server**: `authMiddleware` no longer calls `logger.error` for expired tokens — expiry is expected behaviour, not an error. Only tampered signatures and malformed tokens (genuinely suspicious) still log.
- **Client**: `fetchJson` now handles 401 responses by clearing `elysium_token` and `elysium_save_signature` from localStorage and redirecting to `/`. Players whose 30-day token has expired will see the login page instead of a stuck "Invalid or expired token" error screen with no recovery path.
