Google Calendar integration for booking notifications

Browse Source 
- New GoogleCalendar library: createEvent/updateEvent/deleteEvent via service account, all wrapped in try/catch so failures never break booking flow
- booking_process: creates worker + owner calendar events on new booking
- manage_booking_process: deletes old events, creates new ones on modify
- manage_booking_cancel: deletes events before cancellation
- Service_model: updateBookingCalEvents() stores gcal event IDs
- Admin worker form: Google Calendar ID field added
- PHPMailer: enabled exceptions (was silently swallowing SMTP errors)
- Config: application/config/google_calendar.php for service account path + Evelin calendar ID

DB migration required:
  ALTER TABLE workers ADD COLUMN google_calendar_id VARCHAR(255) NULL DEFAULT NULL;
  ALTER TABLE bookings ADD COLUMN gcal_event_id_worker VARCHAR(255) NULL DEFAULT NULL;
  ALTER TABLE bookings ADD COLUMN gcal_event_id_owner VARCHAR(255) NULL DEFAULT NULL;
