On copied or restored files (e.g. a backup library), the OS stamps created at copy time while modified is preserved from the source, so the earlier of the two is a better proxy for when the content originated. Adds utils::earliest_fs_time and threads it through the three spots that fall back to filesystem dates: photos-list sort, memories grouping, and insight-generation timestamp.
