fix(settings): restore archive password list

Load the stored archive password list through a dedicated trusted IPC channel when extraction settings are opened. Preserve write-only drafts across settings and account updates, guard unsaved edits against late responses, and invalidate stale loads during backup imports. Prepare version 2.0.46 with public release notes.
