feat: surface moderation data in federation admin + Mastodon API

1. Federation admin page (/admin/federation): new Moderation section
   showing blocked servers (with hostnames), blocked accounts, and
   muted accounts/keywords

2. GET /api/v1/domain_blocks: returns actual blocked server hostnames
   from ap_blocked_servers (was stub returning [])

3. Relationship responses: domain_blocking field now checks if the
   account's domain matches a blocked server hostname (was always false)
