feat(content+admin): home-events CRUD + comments moderation

- content-svc: home-events gains Create/Update/Delete + includeInactive list
  (POST/PUT/DELETE /v1/home-events, admin-gated; dates coerced to UTC)
- admin /admin/home-events: full CRUD for homepage hero event banners
- admin /admin/comments: list + approve/unapprove + delete (moderation)
- AdminResource: optional listQuery to fetch inactive rows for admin views

Fills the remaining legacy-admin gaps (home events, comments).
