Two related fixes so the app never silently presents itself as
a demo when it is in fact running against a real hub:
- The orange 'Demo-Daten · KEINE Rechtsberatung' banner was
hard-coded into every data screen, regardless of whether
the active repository was the in-memory MockRepository or
the live HubRepository. Replaced with ModeBanner, which
picks one of three voices by repository.mode:
demo orange T4 — 'Demo-Daten · KEINE Rechtsberatung'
hub-live petrol — 'Live aus Hub · <endpoint>'
hub-down warm-warn — 'Hub nicht erreichbar — leere Liste'
- main.dart's _pickRepository used to fall back to
MockRepository whenever HubRepository.connect() came back
unhealthy. That silently downgraded a live deployment to
demo data, which is exactly what the user is trying to avoid.
Removed: when useHub=true, the HubRepository is returned
regardless. Its list() returns [] on hub-down, and the
'hub-down' banner explains why the screens are empty.
Mock data only shows when the user explicitly turns useHub
off in the Hub-Reiter.
Also: legend arrow icons now point in the actual axis direction
(→ for Schaden, ↑ for Nutzen) instead of the bidirectional ↔/↕,
which suggested the axes ran both ways. Mini-chips and the
expanded legend rows are consistent.
