fix(app): finish an editor save after recreation

A successful save left saving set while the destination committed in
the activity's lifecycleScope. An activity recreated then (theme,
locale, split-screen resize) cancelled that scope: onSaved never ran,
and the surviving ViewModel kept Save disabled and back swallowed.

The ViewModel now keeps the success in a memory-only saved state, set
inside the NonCancellable write so a cancelled caller cannot lose it.
A LaunchedEffect on it runs the commit and onSaved, so a recreated
editor finishes the job; "Save and copy" and the stale-original notice
run once only, and left() clears it before onSaved navigates.

Editing a symlinked entry derived its folder from the canonical path
but its name from the link, saving a new entry next to the target. The
folder is now relative to the non-canonical repository directory; the
save still checks the target is inside the store.
