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

+> Get your internal IP address
+
+
+## Install
+
+```

+
+
+## Usage
+
+```js
+const internalIp = require('internal-ip');
+
+(async () => {

+	//=> 'fe80::1'
+
+	console.log(await internalIp.v4());

+//=> '10.0.0.79'
+```
+
+The module returns the address of the internet-facing interface, as determined from the default gateway. When the address cannot be determined for any reason, `null` will be returned.
+
+The module relies on operating systems tools. On Linux and Android, the `ip` command must be available, which depending on distribution might not be installed by default. It is usually provided by the `iproute2` package.
