Fix Duplicate Fields Left by JCMA Migration

After migrating from Jira Data Center to Cloud, the Jira Cloud Migration Assistant (JCMA) creates duplicate custom fields with a "(migrated)" suffix. Migration Helper detects every duplicate and merges them safely -- no scripting, no data loss.

JCMA Leaves Duplicate Custom Fields Behind

The Problem:

JCMA creates copies of every custom field with "(migrated)" suffix
Multiple migrations create "(migrated 2)", "(migrated 3)", etc.

With Migration Helper:

Scans all custom fields and detects "(migrated)" suffix pairs
Safe merge -- copies migrated values only when original is empty
Preview every field pair before committing the merge
Batch processing with cursor-based pagination for thousands of issues

Scan screen showing detected duplicate pairs with safety classification and affected issue counts
