fix(federation): enforce the signature policy on incoming requests
HTTPSignaturePlug checks the policy before the cryptographic check. A
signed GET that fails it counts as unsigned; the inbox answers 401 to a
POST that fails it instead of queueing a failed-signature retry, which
only re-checks the signature. signature_policy: :log only logs.

Based on Akkoma's HTTP signature hardening.

Reject incoming HTTP signatures that do not sign the date, are older than 2 hours (or more than 1 hour in the future), or do not sign the digest of a request body, so captured requests cannot be replayed. Set `config :pleroma, :activitypub, signature_policy: :log` to only log these
