Rollbacks in move_file, apply_rename and undo/redo no longer ignore
errors: every move that can't be undone is reported (old -> new), and the
catalog follows the files that kept their new names (an undoable partial
rename; a logged change for undo/redo), so nothing shows as missing.
A file that can't go back keeps the sidecars that moved with it.
library.findMissing: same name + size confirmed by the stored content
hash first, then renamed files by size + content hash, then a unique
name + size match; several look-alikes are skipped and reported in
'ambiguous' instead of guessed. Files already used by a photo are skipped.
Stacked on fix/issue-95-case-only-rename (same functions).
