- ServicesProvider: add blockSlot() calling POST /services/block and
unblockSlot() calling PATCH /services/:id/status with cancelled
- ProfessionalCalendarView:
- Fix _services always-null bug: getServicesForProfessional() returns
void; now reads from sp.services after it resolves
- Differentiate self_booked (blocked) vs regular occupied slots
- Show amber 'Bloqueado' state with lock icon for self_booked services
- Show lock button on available slots → confirm dialog → blockSlot()
- Show unlock button on blocked slots → confirm dialog → unblockSlot()
- Reload calendar after block/unblock so UI reflects new state
- Header stats now show separate counts: ocupadas / bloqueadas / libres
- _ActionButton widget for reusable tap-target icon buttons
