Order database table display by insertion order (ROWID) instead of timestamp

Changed the data retrieval query to use ROWID DESC instead of timestamp DESC, ensuring that the most recently inserted data appears first regardless of timestamp field values. This fixes the issue where entries with "not connected" or invalid timestamps would appear in wrong order.

Benefits:
- Most recent database entries always shown at top
- Works correctly even when timestamp is null, "not connected", or incorrect
- Based on actual insertion order rather than timestamp field
