Create a Cal.com event type via API v2 with locations and booking limits

Documented steps

1. POST https://api.cal.com/v2/event-types with headers: cal-api-version: 2024-06-14, Authorization: Bearer <api_key>, Content-Type: application/json
2. Required body: {"title": "...", "slug": "...", "lengthInMinutes": <number>}
3. Optional locations array, e.g. {"locations": [{"type": "address"|"link"|"integration"|"phone"|..., ...}]} — v2 uses plain type names, not the v1 'integrations:' prefix
4. Optional limits and policies: bookingLimitsCount ({limit, timeUnit}), bookingLimitsDuration, minimumBookingNotice, beforeEventBuffer/afterEventBuffer, slotInterval, bookingWindow, seats, recurrence, confirmationPolicy, bookingFields, disableGuests, successRedirectUrl
5. Response: 201 with {status: 'success', data: {id, title, slug, lengthInMinutes, ...}} — store data.id for slots queries and bookings
