Delegation Integration & Flight Improvements

New

• Delegation across all features -- Delegation now works end-to-end across orders, reservations, bookings, travelers, policies, budgets, and document management
• Delegate visibility -- Booking requests and order detail views now show who booked on behalf of whom
• Flight passenger limits -- Flight search and booking enforce a maximum passenger count with validation
• Traveler age validation -- Traveler ages are validated against passenger types (adult, child, infant) during booking with localized error messages
• Cabin class selector -- Desktop flight search results now include a cabin class filter with mobile drawer support
• Booking state persistence -- Flight selection, hotel details, and traveler assignments now survive page refreshes and language switches, with automatic expiry after the search token's 1-hour lifetime
• Form error auto-scroll -- Forms across the booking app automatically scroll to the first error on submission

Improved

• Budget form validation and conditional field behavior refined with improved settings UX
• Flight sort options changed from dropdown to inline pill buttons for faster access
• Flight search components memoized for better rendering performance
• Delegation grant dialog rebuilt with user search and simplified scope selection
• Trip type hint badge added to the sticky date field on flight search
• Hotel name search on desktop now debounces input to reduce unnecessary API calls

Fixed

• E-ticket download now works for all travelers in a reservation, not just the first
• Policy status badge on booking review is always clickable regardless of violation state
• Delegation scope dependencies are enforced correctly and cache invalidation works on scope changes
• Per-traveler-type pricing is passed through correctly from the provider and shown in the price breakdown
• Table action buttons no longer trigger row click events in the dashboard
• Hotel address text no longer overflows its container
• Empty hotel search results are handled gracefully instead of showing a blank page
• Country code badge displays correctly across all views
• Policy effective date range is validated when assigning policies to users
• Location input clears on focus for consistent search behavior
• API client skips retries on 4xx client errors to avoid redundant requests
• Policy variable shadowing fixed in flight evaluation logic
• Traveler form submission no longer bubbles to parent search form
• Booking review page no longer allows submission when traveler selection is empty
