✨ Enhance timezone support across application

- Introduced a `SetTimezone` middleware to dynamically apply user-specific timezones.
- Added a `timezone chooser` component for users to select their timezone.
- Enhanced date and time display in views with `asDate`, `asTime`, and `asDateTime` methods.
- Updated `AppServiceProvider` to leverage `preventLazyLoading` in local environments and set custom `Carbon` instance for dates.
- Expanded configuration with `user-timezone`.
- Integrated timezone support into meetups and events for consistent scheduling.
