Brings the Flutter app to parity with the recent Web App changes, which
touched features the Phone App did not yet have — so this builds the
Charging and Integrations subsystems, then applies the tab/fold structure.
Charging (new nav destination): split into "Public chargers" (stylized
discovery map + demo session + nearby public stations) and "Home chargers"
(the real Anker Solix OCPP control card — serial refresh, connector/energy
tiles, start/stop, current limit, password step-up on reset — plus the
user's home charger list). Gated by the per-user control mode, degrading to
a Settings hint when off.
Settings: split into "Personal settings" (the existing account/appearance/
profile/security/privacy/danger sections) and "Integrations". The latter
holds foldable Toyota and Anker Solix cards over the superadmin -> org ->
user cascade: locked fields with "inherited from" notes, org-admin scope
switch, enable toggle, save/test with health result, and Anker OCPP token
provisioning. Both tabs stay mounted (IndexedStack) so in-flight edits
survive a switch.
Adds the integration + OCPP control endpoints to api.dart, the resolved
IntegrationView/Scope/Field, IntegrationHealth and AnkerControl models, and
charging.*/settings.tabs.*/nav.charging strings (en/pl/da) plus
settings.integrations.* (en) — mirroring the Web App's own pl/da coverage,
which leaves integrations and charger control untranslated as an English
fallback.
