When splitting one operation into misc and tasks operations:
- Both operations now get unique ID suffixes (_misc and _tasks)
- Skip logic verifies both conditions before skipping:
1. tasks config has migrated field (isConfirmBeforeDelete)
2. misc config has NO migrated fields remaining
This prevents:
- Potential operation ID conflicts in the sync log
- Data loss in partial migration scenarios
Adds test cases for partial migration and correct skip scenarios.
