Assert relay inbox response statuses

Check for 202 Accepted at all 14 previously discarded inbox responses
in the LitePub and Mastodon relay tests. This prevents follower-store
assertions from hiding errors returned by the inbox handler.

#1046

Validated with mise run test-each relay, including code checks and
Deno, Node.js, and Bun tests.
