Add SQL script to reset reports sync data for full resync

- Add RESET_REPORTS_SYNC.sql with multiple reset options
- Option 1: Reset for specific client
- Option 2: Reset for ALL clients (full reset)
- Option 3: Reset for multiple specific clients
- Option 4: Reset syncs after specific date
- Include verification queries to confirm deletion
- Include auto-increment reset option

This allows administrators to:
- Force clients to perform full resync
- Reset corrupted sync data
- Clean up old sync records
- Verify deletion was successful

+-- ============================================
+-- Notes
+-- ============================================
+
+-- 1. Replace 'YOUR_CLIENT_ID_HERE' with actual client ID
+-- 2. For Option 2 (Full Reset), comment out other options
+-- 3. For Option 3, add/remove client IDs as needed
+-- 4. For Option 4, adjust date as needed
+-- 5. Run verification queries after reset to confirm
+-- 6. Auto-increment reset is optional - only if you want clean IDs
+
+-- After running this SQL:
+-- - All clients will query /api/reports/last-sync and get "No sync records found"
+-- - Clients will perform full sync on next sync attempt
+-- - All historical data will be re-sent to server
