Admin-only endpoint for recovering from needs_attention. Deletes the
local peer row; FK cascade removes queued outbox entries. Gated to
peers in needs_attention to prevent accidental resets of healthy
peerings (use /peers/:id for revoke on active peers).
Also extends the Task 8.5 test mock of '../db/index.js' to re-export
`schema`. federation.ts imports `schema` from the re-export alongside
`getDb`; the previous mock only exposed `getDb`, causing the route
handler to blow up with 500s before reaching any assertion. This is
a scaffolding fix — no test assertions were changed.
Four cases from the spec's testing strategy: 404 on missing peer, 400 on
wrong status, 403 for non-admin, and successful delete including FK
cascade of queued outbox entries. Introduces a minimal Fastify-inject
harness for route testing — previously the codebase had only pure-function
unit tests under utils/.
Tests intentionally FAIL at this commit — Task 8 will add the handler and
close the loop.
