🎉 **Introduce meetup activity management**

- Added `is_active` and `last_event_at` fields to meetups with migration.
- Enhanced UI: Display `Aktiv`/`Inaktiv` badges and last event dates across dashboard, tables, and maps.
- Introduced `/meetups:update-activity` command to manage activity flags and timestamps.
- Validated latitude/longitude to prevent `0,0` inputs in city creation and updates.
- Updated factories and tests to include meetup activity states (`active`, `inactive`).
