✨ Enhance meetup association and permissions management

- 🔍 Added `resolveInScope` method to `ResolvesEntities` for scoped entity resolution with stricter control.
- 👥 Introduced `AddMeetupToMineTool` MCP tool for adding external meetups to "My Meetups."
- 🛠️ Updated `ListMyMeetupsTool` and `ShowMyMeetupTool` to include both created and joined meetups.
- 📚 Updated `Meetup` model with `associatedWith` scope for querying user-related meetups.
- ✅ Expanded feature tests for meetup membership, creator permissions, and scoped tool usage.
- 🛡️ Unified access checks across Livewire and APIs to restrict editing meetup details to creators or super-admins.
- 🔗 Registered `AddMeetupToMineTool` in `EinundzwanzigServer`.
