feat: rental drafts, room modal cleanup, tariff auto-code

- New hotels get 3 rental object templates (tennis/sauna/conference) as drafts (is_active=false)
- RentalPage: draft templates shown separately with Activate/Delete buttons
- Migration 047: adds is_active column to rental_objects
- RoomModal: hide bed type/status/housekeeping in create mode; optional price (from category); restructured Places tab with extra beds constructor
- TariffsPage: auto-generate tariff code from name initials if code field is empty
- types: ExtraPlace.beds for extra place bed configuration
