fix: align PHP requirement and implement rate limiting

- Update composer.json to require PHP ^8.3 (required by grazulex/laravel-apiroute ^1.2)
- Add rate limiting to routes using laravel-apiroute's rateLimit() and Laravel's throttle middleware
  - Public routes (login/register): throttle:auth (5/min for brute force protection)
  - Protected routes: throttle:authenticated (120/min)
  - Global version rate limit: 60 req/min via ->rateLimit(60)
- Remove unused import in routes/web.php (fixes Pint style issue)
- Update composer.lock with synchronized dependencies
