Public booking API now rejects a 6th active booking from the same
customer_contact within 24h (429), stopping one contact from filling
every slot on every resource, while owner-entered manual bookings stay
unaffected.
Add POST /api/contact: client sites can reach their own owner's inbox
directly (via their existing login email) for general inquiries,
separate from the agency's leads/Telegram pipeline (n8n/lead-intake.json),
which stays reserved for actual prospects contacting the agency itself.
Paris Barber Shop's contact form and Rückruf widget now point here; the
Rückruf floating widget itself has been removed from the site.
