Needed for eMxInfo.txt (site-specific eDNC config). The file has no
DisplayVersion in the registry and no canonical MSI; we ship it as a
standalone secret on the SFLD share and key drift correction off its
SHA256. When the yearly replacement drops, bump the hash in
machineapps-manifest.json and every Standard-Machine PC catches up on
next logon.
Patched Install-FromManifest in all three copies (CMM, common, Standard)
for consistency. Also adds the eMxInfo.txt entry to the Standard
machineapps-manifest template and an Install-eMxInfo.cmd template that
copies the file into both 32/64-bit eDNC Program Files paths.
