FuelBoard Contributor bfeb494c03 Offline banner: label the bundled-dump fallback with its snapshot date
The no-network last resort (bundled real dump) now shows a tappable banner
above the tabs — 'Offline data from 15 Aug / Pull to refresh to update
prices' — so stale snapshot data is never presented as live. Banner date
comes from the dump's own data_updated stamp (FuelStore.offlineDataLabel,
ISO 8601 with/without fractional seconds). Cleared on any successful fetch.

- BundledDumpProvider.dataUpdatedStamp (JSONSerialization, app target)
- ContentView: offlineDataDate state, offlineBanner view (tip-card styling,
  orange wifi.slash + arrow.clockwise, tap = force refresh), refresh()
  clears/sets it, -forceOfflineDump QA launch hook (serves the dump and
  skips auto-refresh so the banner stays up for captures)
- Localizable.strings: 3 keys (banner title/subtitle/a11y)
- +3 tests: OfflineDataLabelTests (101 total)

// BundledDumpProvider.swift — no-network last resort (P0 live chain).
//
// A REAL snapshot of the mirror dump is bundled into the app (FuelBoardDump
// dataset, refreshed before builds by scripts/refresh_bundled_dump.sh) so the
// app never demos empty and App Review always sees real data even fully
// offline. Same relay envelope, so the shared decode applies unchanged.
