Google Calendar integration for booking notifications

- 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; Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
