fix: robust first-launch auto-preload (mobile bible/download)

- OfflineManager.preload accepts bibleTranslations: 'all' and resolves
  translation ids internally from versions.json (single source), removing
  the fragile settings-side fetch that could throw and abort the whole
  download on mobile first launch
- Decouple trigger from '#settings/autopreload' route param via one-shot
  requestAutoPreload()/consumeAutoPreload() flag
- Auto-expand + tick Bible variant checkboxes for UI consistency
- Offer modal sets the flag and navigates to plain '#settings'
