geenforce: HTTPS payload delivery (content-addressed blob store + endpoint)

Lets share-less (Intune/local-account) PCs pull installers the manifest
references over HTTPS instead of SMB - the general capability the whole fleet
migrates toward. New ManifestBlob registry (migration 0002) with bytes on disk
at instance/geenforce/payloads/<sha256> (deduped by content); service.store_blob
+ blob_path; client-facing GET /api/geenforce/payload/<sha256> (geenforce.fetch
token, ETag=hash, serves the blob store or an inline DB payload by hash). The
serializer now emits PayloadSource/PayloadSha256/PayloadRef for http/inline
entries only (smb entries round-trip unchanged - parity green). CLI
'flask geenforce add-payload <file>' registers a blob and prints its sha256.
This is the shopdb half (B1); the PS client/engine fetch is B2.
