Cancel a confirmed booking and process the Stripe refund per host cancellation policy. Use when the guest explicitly requests cancellation — if the guest wants new dates instead of ending the stay, use hemmabo_booking_reschedule instead. Do not use for pending/unpaid bookings — those expire automatically. To preview the applicable policy first, read cancellationPolicy from hemmabo_booking_status. Requires Authorization: Bearer token (MCP_API_KEY or OAuth). Destructive and idempotent: cancelling an already-cancelled booking returns the same status. Rate-limited per token. reservationId must be the booking UUID from hemmabo_booking_checkout or hemmabo_booking_create — not a propertyId; reason is optional free text forwarded to the host.
