convert_begin_offset_to_file_pos can undershoot, in which case the metadata returned by the archival policy won't perfectly align with the caller's expectations. This could result in an offset_overlap when applying the upload metadata. It's unclear exactly why there are missing batches, given this code is used for the non-compacted uploader. But the fix is simple enough, and is one that we use in the compacted upload policy already[1].

The headers are often a go-to place for information about the behavior callers should expect from a method. Adds some details explaining at a high level what to expect from a couple of methods. (cherry picked from commit ff120d0)
