feat(mcp): add compound tools for common multi-step workflows

Browse Source 
Adds three atomic compound MCP tools that collapse invariant sequential
call patterns into single operations with transaction-backed rollback:
- create_and_assign_place: create place + assign to day
- create_place_accommodation: create place + book accommodation
- create_budget_item_with_members: create budget item + set split members
