v1.9.0

Added

• vsps_form_started event when the booking form opens (form started → completed funnel).
• vsps_after_hours (true/false, computed server-side against the clinic's real hours in its timezone) and vsps_booked_at on vsps_booking_completed — powers the 'booked outside office hours' metric.
• Booking source label setting: tags appointments sent by the widget (Vetspire reason + admin badge), e.g. 'Vetcelerator'.

Changed

• Neutralized layout naming in code and demo copy.
