fix: restore ArchiveTeam Warrior as a proper integration

The widget-only integrations refactor incorrectly removed the
ArchiveTeam Warrior integration entirely. It only needed to be
excluded from auto-seeding (by removing defaultUrl), not deleted.

This restores the integration class, reverts the widget/router/handler
to use integration middleware, and removes archiveTeamWarrior from the
widget-only-integrations migration.
