Summary

• The periodic mirror check task (mirror-check.js / mirror-check-v2.js) ensures mirrors exist for org_uid, registry_id, and data_model_version_store_id stores, but was missing the file_store entirely
• When the initial mirror creation during org creation fails (e.g., wallet temporarily unsynced), the file_store mirror was never retried by the periodic task, causing the CI test's organization mirror validation to fail
• Added file_store mirror creation to both V1 and V2 mirror check tasks so it is retried on the periodic schedule like all other org stores

Root Cause Analysis

From CI run #22002605727:

1. During org creation at 21:11:53, the add_mirror RPC call for the file_store (3a8b8ee6...) failed with "Wallet needs to be fully synced before making transactions"
2. After org creation completed, runMirrorCheckV2() was triggered at 21:14:24 to retry any failed mirrors
3. The mirror check successfully created/verified mirrors for org_uid, registry_id, and data_model_version_store_id
4. But it never attempted the file_store mirror because the code simply didn't include it
5. Test validation found 0 mirrors for the file_store and failed

Test plan

• Re-run the v2 live API tests to verify the file_store mirror is created by the periodic mirror check
• Verify the V1 mirror check also handles fileStoreId correctly
