🗓️ Add MeetupEventFactory, implement rate limiting for calendar downloads, and enhance test coverage

- **Added:** `MeetupEventFactory` for generating test data.
- **Implemented:** Rate limiting (`throttle:calendar`) for `stream-calendar` routes to prevent abuse.
- **Enhanced:** `DownloadMeetupCalendar` controller with validation and cleaner query structure.
- **Added:** Feature tests for calendar downloading, invalid input handling, and rate limiting.
