pushsync: add unsigned receipts to verify in-neighborhood replication peers accepted chunk and can be accounted for

This quick-fix prevents the mantaray manifest IterateAddresses method
walker to fail when it encounters an empty address, otherwise, the unpin
traversal operation for the manifest fails.

Several inconsistencies declared in the pins and stamps endpoints
of the OpenAPI specification and the bee API server implementation
are removed. On top of that also fixes several declaration errors.
