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

+
+A simple API for interacting with binary and plain text
+[plist](https://en.wikipedia.org/wiki/Property_list) data.
+
+## Installation
+
+```sh
+# via npm
+npm install simple-plist
+
+# via yarn
+yarn add simple-plist
+```
+
+## Synchronous API
+
+```js
+const plist = require("simple-plist");
+
+let data;
+
+// read
+data = plist.readFileSync("/path/to/some.plist");
+
+// write xml
+plist.writeFileSync("/path/to/plaintext.plist", data);
+
+// write binary
+plist.writeBinaryFileSync("/path/to/binary.plist", data);
+```
+
+## Asynchronous API
+
+> Note: all of the async examples can optionally be converted to promises using
+> node's [`util.promisify`](https://nodejs.org/dist/latest-v8.x/docs/api/util.html#util_util_promisify_original).
+
+```js
+const plist = require("simple-plist");
+
+let data;
+
+function callback(err, contents) {
+  if (err) throw err;
+  data = contents;
+}
+
+// read
+plist.readFile("/path/to/some.plist", callback);
+
+// write xml
+plist.writeFile("/path/to/plaintext.plist", data, callback);
+
+// write binary
+plist.writeBinaryFile("/path/to/binary.plist", data, callback);
+```
+
+## In Memory
+
+### `plist.stringify()`
+
+```js
+const plist = require("simple-plist");
+
+// Convert an object to a plist xml string
+plist.stringify({ name: "Joe", answer: 42 });
+
+/*
+<?xml version="1.0" encoding="UTF-8"?>
+<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
+<plist version="1.0">
+  <dict>
+    <key>name</key>
+    <string>Joe</string>
+    <key>answer</key>
+    <integer>42</integer>
+  </dict>
+</plist>
+*/
+```
+
+### `plist.parse()`
+
+```js
+const plist = require("simple-plist");
+
+const xml = `<plist>
+	<dict>
+		<key>name</key>
+		<string>Joe</string>
+	</dict>
+</plist>`;
+
+plist.parse(xml);
+// { "name": "Joe" }
+```
+
+## TypeScript Support
+
+All functions have typescript signatures, but there are a few handy generics
+that are worth pointing out. Those generics belong to `parse`, `readFile`,
+and `readFileSync`. Here's an example:
+
+```tsx
+import { parse, readFile, readFileSync } from "simple-plist";
+
+type Profile = {
+  name: string;
+  answer: number;
+};
+
+const xml = `<plist>
+	<dict>
+		<key>name</key>
+		<string>Joe</string>
+		<key>answer</key>
+		<integer>42</integer>
+	</dict>
+</plist>`;
+
+// typed string parsing
+const { answer } = parse<Profile>(xml);
+// answer = 42;
+
+// typed file loading
+const { name } = readFileSync<Profile>("/path/to/profile.plist");
+```
