feat: wire slot reservation into all booking flows

Customer flow: reservation fires on Date/Time → Details transition with
re-validation on time slot tap and on 'Next' click to prevent simultaneous
bookings. 5-step flow: Service → Date/Time → Reserve → Details (countdown)
→ Payment & Review → Confirm. Guest users redirected to home on success.

Admin call-in: reserve slot before final submission (60min TTL).
Admin walk-in: reserve slot on modal open (5min TTL).
