feat: serve all precached data offline via DataCache fallback

- DataCache.fetchWithFallback: network-first with IDB write-through under
  the same url: keys the preload writes; falls back to precached IDB copy
  when offline — closes the preload(IDB) vs read(SW cache) gap that made
  the Bible reader (and every other view) fail offline despite precaching
- Convert all 33 raw /data fetches across bible/service/menaion/prayer/
  calendar/settings views; in-memory caches and notFound maps preserved
- fetchCommandText: switch to lowercase services/commands/ (already in
  preload manifest); tolerate both TEXT/text node casings per migrate-data
- Remove stale duplicate static/data/en/services/Command/ (15 files)
- fetchLives: fix misc fallback to real lives/misc/{N}.json bundles
