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

+@protocol
+@abstract JSExport provides a declarative way to export Objective-C objects and
+ classes -- including properties, instance methods, class methods, and
+ initializers -- to JavaScript.
+
+@discussion When an Objective-C object is exported to JavaScript, a JavaScript
+ wrapper object is created.
+
+ In JavaScript, inheritance works via a chain of prototype objects.
+ For each Objective-C class in each JSContext, an object appropriate for use
+ as a prototype will be provided. For the class NSObject the prototype
+ will be the Object prototype. For all other Objective-C
+ classes a prototype will be created. The prototype for a given
+ Objective-C class will have its internal [Prototype] property set to point to
+ the prototype created for the Objective-C class's superclass. As such the
+ prototype chain for a JavaScript wrapper object will reflect the wrapped
+ Objective-C type's inheritance hierarchy.
+
+ JavaScriptCore also produces a constructor for each Objective-C class. The
+ constructor has a property named 'prototype' that references the prototype,
+ and the prototype has a property named 'constructor' that references the
+ constructor.
+
+ By default JavaScriptCore does not export any methods or properties from an
+ Objective-C class to JavaScript; however methods and properties may be exported
+ explicitly using JSExport. For each protocol that a class conforms to, if the
+ protocol incorporates the protocol JSExport, JavaScriptCore exports the methods
+ and properties in that protocol to JavaScript
+
+ For each exported instance method JavaScriptCore will assign a corresponding
+ JavaScript function to the prototype. For each exported Objective-C property
+ JavaScriptCore will assign a corresponding JavaScript accessor to the prototype.
+ For each exported class method JavaScriptCore will assign a corresponding
+ JavaScript function to the constructor. For example:
+
+<pre>
+@textblock
+    @protocol MyClassJavaScriptMethods <JSExport>
+    - (void)foo;
+    @end
+
+    @interface MyClass : NSObject <MyClassJavaScriptMethods>
+    - (void)foo;
+    - (void)bar;
+    @end
+@/textblock
+</pre>
+
+ Data properties that are created on the prototype or constructor objects have
+ the attributes: <code>writable:true</code>, <code>enumerable:false</code>, <code>configurable:true</code>. 
+ Accessor properties have the attributes: <code>enumerable:false</code> and <code>configurable:true</code>.
+
+ If an instance of <code>MyClass</code> is converted to a JavaScript value, the resulting
+ wrapper object will (via its prototype) export the method <code>foo</code> to JavaScript,
+ since the class conforms to the <code>MyClassJavaScriptMethods</code> protocol, and this
+ protocol incorporates <code>JSExport</code>. <code>bar</code> will not be exported.
+
+ JSExport supports properties, arguments, and return values of the following types:
+
+ Primitive numbers: signed values up to 32-bits convert using JSValue's
+ valueWithInt32/toInt32. Unsigned values up to 32-bits convert using JSValue's
+ valueWithUInt32/toUInt32. All other numeric values convert using JSValue's
+ valueWithDouble/toDouble.
+
+ BOOL: values convert using JSValue's valueWithBool/toBool.
+
+ id: values convert using JSValue's valueWithObject/toObject.
+
+ Objective-C instance pointers: Pointers convert using JSValue's
+ valueWithObjectOfClass/toObject.
+
+ C structs: C structs for CGPoint, NSRange, CGRect, and CGSize convert using
+ JSValue's appropriate methods. Other C structs are not supported.
+
+ Blocks: Blocks convert using JSValue's valueWithObject/toObject.
+
+ All objects that conform to JSExport convert to JavaScript wrapper objects,
+ even if they subclass classes that would otherwise behave differently. For
+ example, if a subclass of NSString conforms to JSExport, it converts to
+ JavaScript as a wrapper object rather than a JavaScript string.
+*/
+@protocol JSExport
+@end
+
+/*!
+@define
+@abstract Rename a selector when it's exported to JavaScript.
+@discussion When a selector that takes one or more arguments is converted to a JavaScript
+ property name, by default a property name will be generated by performing the
+ following conversion:
+
+  - All colons are removed from the selector
+
+  - Any lowercase letter that had followed a colon will be capitalized.
+
+ Under the default conversion a selector <code>doFoo:withBar:</code> will be exported as
+ <code>doFooWithBar</code>. The default conversion may be overridden using the JSExportAs
+ macro, for example to export a method <code>doFoo:withBar:</code> as <code>doFoo</code>:
+
+<pre>
+@textblock
+    @protocol MyClassJavaScriptMethods <JSExport>
+    JSExportAs(doFoo,
+    - (void)doFoo:(id)foo withBar:(id)bar
+    );
+    @end
+@/textblock
+</pre>
+
+ Note that the JSExport macro may only be applied to a selector that takes one
+ or more argument.
