Booking requests now complete end-to-end over HTTP:
- _to_sats() converts fiat->sats via fiat_amount_as_satoshis (sat/sats
pass through). This is the single conversion point; the result is the
canonical amount_sat and is not recomputed downstream.
- api_request_booking creates a sats-denominated deposit invoice (locked
amount, immune to FX drift before payment), tagged {tag:chatelet,
booking_id} so tasks.on_invoice_paid matches the settle. On InvoiceError
the hold is released (status=declined) so dead holds don't block dates.
- New BookingQuote response returns the held booking + bolt11 + hash.
Settlement (tasks.on_invoice_paid: awaiting_payment -> confirmed, dates
hard-blocked, reservation republished) was already in place and now fires
on real payments. Testable on FakeWallet.
