feat(GRO-1792): add recovery paths to booking error and cancellation pages

- Add "Start a new booking" button to BookingError linking to /admin/book
- Add "Book again" button to BookingCancelled linking to /admin/book
- Add business contact info section to BookingError (from BUSINESS_CONTACT_INFO constant)
- Replace hardcoded colors with CSS variables (--color-error, --color-cancelled, etc.)
- Add page-level string constants to eliminate hardcoded strings
- Add unit tests for both pages (9 tests passing)
