fix: simplify background heal and trigger heal items early (#9928)

Bonus fix during versioning merge one of the PR was missing
the offline/online disk count fix from #9801 port it correctly
over to the master branch from release.

Additionally, add versionID support for MRF

Fixes #9910
Fixes #9931
