Add occupancy analytics, housekeeping maintenance notes, and booking widget form flow

- DynamicPricingPage: add 'Нагрузка' tab with monthly occupancy bar chart (2025/2026 data), year selector, summary stats, and editable occupancy-based pricing rules (threshold ranges → price modifiers)
- HousekeepingPage: add maintenance note button (wrench icon) on task cards — housekeeper can report broken items with a description that gets sent to technical service; notes displayed in orange badge
- BookingWidgetPage: fix 'Забронировать' button with full form flow (browse → form → success), add configurable form fields (required/optional/custom), add additional services toggle in settings and at checkout, add extra beds + children count in guest selector with auto-pricing
