✨ Add ResolvesEntities concern for name-based ID resolution

- 🤖 Introduced `ResolvesEntities` trait to simplify entity resolution by name or ID across MCP tools.
- 📚 Updated tools (Meetups, Cities, Venues, Courses, Lecturers) to use the concern for resolving related entities (e.g., courses, venues, lecturers).
- 🎯 Enhanced tool descriptions and schemas for better name-based parameter handling with fallback support for IDs.
- ✅ Added dedicated feature tests for name resolution logic, partial matches, and error handling scenarios.
