* Use OriginalUri for axum ActivityData
When the inbox path is under a nested `Router`, the received request has a URI
with the common prefix stripped. This causes incoming signatures to be considered
invalid since the path is different (see https://github.com/LemmyNet/activitypub-federation-rust/issues/107#issuecomment-2767428107)
This commit uses `OriginalUri` for URI extraction instead, which will retrieve
the full URI regardless of router nesting
* Use router nesting for local_federation
With 8c787f5, router nesting is supported correctly in axum
* Fix docs typo (#143)
