Fix calendar timezone and group consulting slots by order

Calendar Timezone Fix:
- Add +07:00 timezone offset to date strings in create-google-meet-event
- Fixes 13:00 appearing as 20:00 in Google Calendar
- Now treats times as Asia/Jakarta time explicitly

Single Calendar Event per Order:
- handle-order-paid now creates ONE event for all slots in an order
- Uses first slot's start time and last slot's end time
- Updates all slots with the same meet_link
- Prevents duplicate calendar events for multi-slot orders

Admin Consulting Page Improvements:
- Group consulting slots by order_id
- Display as single row with continuous time range (start-end)
- Show session count when multiple slots (e.g., "2 sesi")
- Consistent with member-facing ConsultingHistory component
- Updated both desktop table and mobile card layouts
- Updated both upcoming and past tabs
