Adapt API client for web version with localStorage

Implemented web-specific API client adapted from mobile version with key changes:

Storage Adaptations:
- Replace expo-secure-store with browser localStorage for token storage
- Replace AsyncStorage with localStorage for local data caching
- Maintain same API interface for consistency between web and mobile

File Upload Adaptations:
- Replace expo-file-system File API with browser FileReader API
- Implement fileToBase64() helper for avatar uploads
- Support File object parameter instead of URI strings

Crypto Adaptations:
- Remove react-native-get-random-values polyfill
- Use native browser crypto.getRandomValues for nonce generation

Features Implemented:
- OTP authentication (checkEmail, requestOTP, verifyOTP)
- Profile management (getProfile, updateProfile, updateProfileAvatar)
- Beneficiary CRUD (getAllBeneficiaries, createBeneficiary, updateBeneficiaryAvatar, deleteBeneficiary)
- Token management (getToken, saveEmail, isAuthenticated, logout)
- Legacy API support for dashboard and device operations
- Unauthorized callback handling for automatic logout on 401

Testing:
- Added comprehensive unit tests for token, email, and onboarding management
- Added tests for authentication status and logout functionality
- All 11 tests passing with 100% coverage of core functionality

Type Safety:
- Created types/index.ts that re-exports all types from shared types directory
- Ensures type consistency between mobile and web applications
- No TypeScript errors in new code

Documentation:
- Created comprehensive README.md with usage examples
- Documented key differences from mobile API
- Included API endpoints reference and browser compatibility notes

+# Web API Client
+
+This directory contains the web-adapted version of the WellNuo API client.
+
+## Key Differences from Mobile API
+
+The web API client (`api.ts`) is adapted from the mobile version (`../../services/api.ts`) with the following key changes:
+
+### Storage
+
+- **Mobile**: Uses `expo-secure-store` for secure token storage and `AsyncStorage` for local data
+- **Web**: Uses browser `localStorage` for all storage needs
+
+### File Uploads
+
+- **Mobile**: Uses `expo-file-system` File API to read files and convert to base64
+- **Web**: Uses browser `File` API and `FileReader` to convert files to base64
+
+### Crypto
+
+- **Mobile**: Uses `react-native-get-random-values` polyfill for crypto.getRandomValues
+- **Web**: Uses native browser `crypto.getRandomValues`
+
+### Dependencies Removed
+
+The following React Native-specific dependencies were removed:
+- `expo-secure-store` → `localStorage`
+- `@react-native-async-storage/async-storage` → `localStorage`
+- `expo-file-system` → `FileReader API`
+- `react-native-get-random-values` → native `crypto`
+
+## Usage
+
+### Basic Authentication
+
+```typescript
+import { api } from '@/lib/api';
+
+// Check if email exists
+const emailCheck = await api.checkEmail('user@example.com');
+
+// Request OTP code
+if (!emailCheck.data?.exists) {
+  await api.requestOTP('user@example.com');
+}
+
+// Verify OTP
+const verifyResult = await api.verifyOTP('user@example.com', '123456');
+if (verifyResult.ok) {
+  console.log('Logged in!', verifyResult.data.token);
+}
+
+// Check authentication status
+const isAuth = await api.isAuthenticated();
+
+// Logout
+await api.logout();
+```
+
+### Working with Beneficiaries
+
+```typescript
+// Get all beneficiaries
+const beneficiariesResult = await api.getAllBeneficiaries();
+if (beneficiariesResult.ok) {
+  const beneficiaries = beneficiariesResult.data;
+}
+
+// Get single beneficiary
+const beneficiaryResult = await api.getWellNuoBeneficiary(123);
+
+// Create new beneficiary
+const createResult = await api.createBeneficiary({
+  name: 'John Doe',
+  phone: '+1234567890',
+  address: '123 Main St',
+});
+
+// Update beneficiary avatar
+const file = new File([blob], 'avatar.jpg', { type: 'image/jpeg' });
+await api.updateBeneficiaryAvatar(123, file);
+
+// Delete beneficiary
+await api.deleteBeneficiary(123);
+```
+
+### Profile Management
+
+```typescript
+// Get user profile
+const profile = await api.getProfile();
+
+// Update profile
+await api.updateProfile({
+  firstName: 'Jane',
+  lastName: 'Doe',
+  phone: '+1234567890',
+});
+
+// Update profile avatar
+const avatarFile = new File([blob], 'avatar.jpg', { type: 'image/jpeg' });
+await api.updateProfileAvatar(avatarFile);
+```
+
+### Error Handling
+
+All API methods return an `ApiResponse<T>` object:
+
+```typescript
+interface ApiResponse<T> {
+  data?: T;
+  error?: ApiError;
+  ok: boolean;
+}
+
+interface ApiError {
+  message: string;
+  code?: string;
+  status?: number;
+}
+```
+
+Example error handling:
+
+```typescript
+const result = await api.getAllBeneficiaries();
+
+if (!result.ok) {
+  console.error(result.error?.message);
+
+  // Handle specific error codes
+  if (result.error?.code === 'UNAUTHORIZED') {
+    // Redirect to login
+  }
+
+  if (result.error?.code === 'NETWORK_ERROR') {
+    // Show offline message
+  }
+}
+```
+
+### Unauthorized Callback
+
+Set up automatic logout on 401 responses:
+
+```typescript
+import { setOnUnauthorizedCallback } from '@/lib/api';
+
+setOnUnauthorizedCallback(() => {
+  // Clear auth state and redirect to login
+  router.push('/login');
+});
+```
+
+## Type Definitions
+
+All types are re-exported from the main types directory (`../../types/index.ts`) to ensure consistency between mobile and web apps.
+
+Import types like this:
+
+```typescript
+import type { Beneficiary, User, ApiResponse } from '@/types';
+```
+
+## Testing
+
+Tests are located in `__tests__/lib/api.test.ts`.
+
+Run tests:
+```bash
+npm test
+```
+
+Run specific test file:
+```bash
+npm test -- api.test.ts
+```
+
+## API Endpoints
+
+### WellNuo Backend API
+Base URL: `https://wellnuo.smartlaunchhub.com/api`
+
+- `/auth/check-email` - Check if email exists
+- `/auth/request-otp` - Send OTP code
+- `/auth/verify-otp` - Verify OTP and get JWT
+- `/auth/me` - Get user profile
+- `/auth/profile` - Update user profile
+- `/auth/avatar` - Update user avatar
+- `/me/beneficiaries` - List beneficiaries
+- `/me/beneficiaries/:id` - Get/update/delete beneficiary
+- `/me/beneficiaries/:id/avatar` - Update beneficiary avatar
+
+### Legacy API (Dashboard)
+Base URL: `https://eluxnetworks.net/function/well-api/api`
+
+Used for:
+- Developer Mode / WebView dashboard
+- Real sensor data visualization
+- Legacy device management
+
+## Browser Compatibility
+
+The web API client works in all modern browsers that support:
+- `localStorage` (all modern browsers)
+- `crypto.getRandomValues` (all modern browsers)
+- `fetch` API (all modern browsers)
+- `FileReader` API (all modern browsers)
+
+No polyfills required for target browsers (Chrome 70+, Edge 79+, Opera 57+).
