component AP gateway: work around encoding bug in Mastodon: Mastodon in wrongly unquoting URL path in `(request-target)`, and thus Libervia was doing the same to check signature. However that doesn't work with Pleroma which is using the path value used in the request (percent-encoded), and thus Pleroma signature were rejected. To work around that, signature is first checked without unquoting, and if this fails a new check is done with unquoting. Bug has been reported at https://github.com/mastodon/mastodon/issues/18871 rel 371
