Merge AI tag maintenance tools

Add an AI tag reset flow across Settings and Explore so AI-generated tags, AI tagging metadata, and stale tagging jobs can be cleared without affecting user tags or other media data. Also add subtle AI source indicators in the tag manager and an Extreme UI Lab scenario for stress-testing large tag/library counts.
test(ui-lab): add extreme mock scenario
