Improved signature handling & instance actor (#8275)
This PR is part of https://codeberg.org/forgejo/forgejo/pulls/4767

It improves the signature handling:
1. move logic to a service (might be used from other services as well)
2. make a clear difference between ` ReqHTTPUserSignature` and `ReqHTTPUserOrInstanceSignature`
3. improve test ability (activitypub/client & distant_federation_server_mock

Adjust instance actor
1. name &
2. webfinger

## Strategy for next PRs is

Integration tests are in the driving seat.

I will step by step add integration tests form original PR and add code required by the integration test changes.
