Fix bug when review pull request commits (#35192)
The commit range in the UI follows a half-open, half-closed convention: (,]. When reviewing a range of commits, the beforeCommitID should be set to the commit immediately preceding the first selected commit. For single-commit reviews, we must identify and use the previous commit of that specific commit. The endpoint ViewPullFilesStartingFromCommit is currently unused and can be safely removed. Fix #35157 Replace #35184 Partially extract from #35077
