feat(documents): syncEntityFolderName + entity-rename hooks

Per-entity subfolder names mirror the entity's current display string.
Wired into updateClient / updateCompany / updateYacht; runs only when
the name field changes. Best-effort (logged + swallowed) so a folder-
sync error never fails an entity update. Preserves the (archived)
suffix when present; skips entirely when the folder has been demoted
to (deleted) — the rep owns the name at that point.
