fix(cache): complete preload coverage + surface silent write failures

Browse Source

Root cause of 'pre-cache done but offline data missing':
1. Preload manifest never listed the services/{prayers,texts,headers,var}
   subtrees the Service view dereferences (CommonPrayers->prayers, etc.),
   plus only 13 hardcoded commands. Generator now enumerates all of them
   (en 1500->1740, ru->1333, cu 1500->2108 files).
2. DataCache.set silently resolved on IDB write failure (quota exceeded),
   so preload counted un-stored files as success and reported 100% done.
   set() now returns boolean; preload treats failed writes as failures
   that feed the existing circuit breaker (visible abort + diag entry).
3. No persistence request: added best-effort navigator.storage.persist()
   before preload, diag-logged.
4. Dropped dead manifest weight (menaion-common/add, horologionadd) -
   never referenced by any view.
