fix(offline): include provided in RTKQ rehydration payload

RTK Query 2.12's invalidation slice reads `provided.tags` during cache
rehydration (`Object.entries(provided.tags ?? {})`). Our persisted
snapshot only carried `{ queries, mutations }`, so `provided` was
undefined and `.tags` threw on every startup with a cached snapshot —
crashing the app inside the rehydrate reducer / immer produce.

Snapshot now carries the real `provided` (so invalidation tags
rehydrate), and `load()` defaults it to `{ tags: {}, keys: {} }` so
snapshots persisted before this field existed recover without a manual
localStorage clear.
