`maestro validate`: print items with status mismatch in list view

[JenySadadia]

maestro validate command output in the list view prints if the status mismatch found in the result but doesn't print items with the status mismatch.

Current output:

• netdev-testing/net-next-hw-2025-10-26--00-00: ❌
  Commit: f092d14e8b16b543b3df4b764147bd623265f501
  Has mismatch but no missing IDs listed

Fix the issue by listing Items with status mismatch.

Note: Table view output of maestro validate prints the list of status mismatch items.
