[feat] Restore group node conversion menu with deprecated label (#4967)

## Summary
- Partially reverts commit c84218d to restore group node functionality
in context menus
- Adds "(Deprecated)" label to indicate the feature is deprecated
- Fixes TypeError when right-clicking on group nodes
- Re-enables tests that were disabled when the feature was removed

## Changes
1. **Restored context menu options** - Added back "Convert to Group Node
(Deprecated)" and "Manage Group Nodes" menu items
2. **Fixed null reference error** - Added null-safe operator to prevent
errors when right-clicking group nodes
3. **Re-enabled tests** - Restored 7 tests that were disabled in commit
586f882

## Test plan
- [x] Right-click on canvas → verify "Convert to Group Node
(Deprecated)" appears
- [x] Right-click on nodes → verify the same menu option appears
- [x] Select multiple nodes and use the menu option → verify conversion
works
- [x] Right-click on group nodes → verify no errors occur
- [x] Run browser tests → verify all re-enabled tests pass
