fix(persistence): reset interrupted downloads to queued on startup and deduplicate LazyStore instance

- Reset items with 'downloading' or 'processing' status to 'queued'
  before re-enqueue on startup to prevent phantom active state
- Include 'processing' status in recovery filter (was a zombie path)
- Remove redundant LazyStore('store.bin') from settingsStore.ts;
  import shared instance from useDownloadStore.ts instead
