✨ **Add authenticated API endpoints for managing Meetups, Cities, Venues, and Lecturers**

- ➕ Introduced `store`, `update`, `mine`, and `mineShow` endpoints for `Meetups`, `Cities`, `Venues`, and `Lecturers` with validation and authorization.
- 🔒 Added `Policies` for `Meetups`, `Cities`, `Venues`, and `Lecturers` leveraging `ChecksCreatorOwnership` for ownership checks.
- 🌐 Created `Resources` for structured API responses: `MeetupResource`, `CityResource`, `VenueResource`, and `LecturerResource`.
- ✅ Added dedicated `Request` classes for input validation: `Store` and `Update` variants for all models.
- 🛠️ Updated controllers to support new functionalities with localized error messages and proper HTTP responses.
