feat: integrate Kleros identity tags

[antoncoding]

Summary

Track Kleros Scout identity tag integration across Monarch account and contract identity surfaces.

Subtasks

• feat: show Kleros identity tags in supplier and borrower lists #536: supplier and borrower lists
• feat: show Kleros identity tags on oracle badges #537: oracle badges

Notes

PR #535 implements the supplier and borrower list integration.

[antoncoding]

Closing the tracker. Supplier/borrower Kleros identity tags shipped via #535/#536. The remaining oracle badge subtask #537 is closed as not planned because current oracle/feed addresses have no Kleros Scout overlap.
