Eric FELIXINE e30ae8ed09 feat(smart-app): implement complete mobile app MVP
- App.tsx: full navigation (Auth stack + Main tabs with 5 screens)
- Auth: LoginScreen, RegisterScreen, ForgotPasswordScreen
- HomeScreen: dashboard with IoT metrics, weather widget, alerts, quick actions, sensors
- MapScreen: interactive map with layer toggles (6 layers)
- MarketplaceScreen: categories (6), products (5), search
- ChatScreen: AI chat with quick prompts (4), bot responses
- ProfileScreen: user info, stats, menu (9 items), logout
- AlertsScreen: alert list with severity, acknowledge
- SensorsScreen: sensor list with type filters (6 types), search
- ZonesScreen: zone cards with stats
- SettingsScreen: language picker (FR/EN/ES/DE), privacy, about
- Stores: iotStore (sensors, zones, alerts), notificationStore, uiStore + i18n
- Hooks: useSensors, useAlerts, useNotifications, useLocation
- Components: Card, Button, LoadingSpinner, ErrorBoundary, Header
- Services: iotService, notificationService (with axios API client)
- Utils: formatters (temp, AQI, noise, dates), validators (email, password, IBAN)
- Theme: colors.ts with full design system (Blue Ocean palette)
- Ditto: fixed MongoDB connection, new JWT secrets, official gateway image

/*
* `wrapManagedObject` and `unwrapManagedObject` are wrapper functions that
* convert ARC-managed objects into `std::shared_ptr<void>` and vice-versa. It's
* a very useful mechanism when we need to pass Objective-C objects through pure
* C++ code, pass blocks into C++ lambdas, and so on.
*
* The idea behind this mechanism is quite simple but tricky: When we
* instantiate a C++ shared pointer for a managed object, we practically call
* `CFRetain` for it once and then we represent this single retaining operation
* as a counter inside the shared pointer; when the counter became zero, we call
* `CFRelease` on the object. In this model, one bump of ARC-managed counter is
* represented as multiple bumps of C++ counter, so we can have multiple
* counters for the same object that form some kind of counters tree.
