feat: hourly pricing + category base prices in booking modal + availability grid

- Add hourly_price column to rate_overrides, base_price/allow_hourly/hourly_base_price to room_categories (migration 033)
- Update categories and rate-overrides backend routes to handle new fields
- AvailabilityPage: hourly/nightly mode toggle, period prices auto-applied to grid with 'П' indicator, confirmation dialog when overriding period prices
- BookingModal: nightly/hourly toggle at top, pricing hierarchy (override → category base → room rate)
- RoomCategoriesPage: base_price/allow_hourly/hourly_base_price fields in category form; inline rooms panel
- CalendarPage + BookingCalendar: pass hourlyPriceOverrides and categoryBasePrices down to BookingModal
