fix: Try raw hash before formatted digest in payload fetch fallback

Browse source 
The previous digest fallback used Display format (source:algorithm:hash)
which caused REST servers to look up files by SHA256 compressed hash
instead of the expected SHA1 primary hash. Now tries raw hash first
(compatible with pkg5 REST servers), then formatted variants with
algorithm info (compatible with local FileBackend storage).
