famfo 77b0275572 feat(activitiypub): enable HTTP signatures on all ActivityPub endpoints (#7035)
- Set the right keyID and use the right signing keys for outgoing requests.
- Verify the HTTP signature of all incoming requests, except for the server actor.
- Caches keys of incoming requests for users and servers actors.
