fix(admin): API key rows clickable with revoke + sync all fixes from master

Syncs all accumulated fixes onto the PR branch:
- API key rows in agents table now open drawer with Revoke button
- API keys show bearer token usage hint instead of config export tabs
- Config export snippets use command language directed at the AI agent
- Styled expired magic link error page
- Hide revoked toggle
- Test cleanup via direct SQL
- All v0.26.2 upstream fixes incorporated
