A history fetch that comes back empty BECAUSE the mirror is unreachable
(pointer probe failed) was only an in-sheet retry card — no global signal.
Now it also raises the red connection banner ('Check your internet
connection / Tap to try again'), so a network problem is visible on every
tab, not just inside the Trends sheet. A successful load clears the
banner (only when the banner is the connection banner — never clobbers
the offline-dump banner).
- TrendsView: onHistoryUnavailable/onHistoryRecovered closures fired from
load() (loadFailed -> unavailable; hasAnyData -> recovered);
-forceHistoryFailure QA hook (forces the unreachable state, skips
auto-refresh like the other force-* hooks)
- FavouritesView: closures threaded through the Trends sheet init
- ContentView: wires them to dataStatus (.live -> .connectionProblem on
failure; recovered clears only .connectionProblem)
- fuelboard-development skill: hook + wiring documented
