# Magic Link Redirect Implementation

## Problem
After clicking a magic link, users would be redirected to the home page (`/`) instead of being taken to their last watched episode.

## Solution
Implemented a redirect flow that:

1. **In `SetEmailVerifiedOnMagicLinkLogin`**: Sets the intended redirect URL in the session using Laravel's standard `url.intended` session key
2. **In `ChooseLanguage` component**: Checks for authenticated users with an intended URL and redirects them appropriately

## Implementation Details

### 1. Session URL Setting (SetEmailVerifiedOnMagicLinkLogin.php)
```php
// Set intended redirect URL for post-login redirect
$redirectUrl = $watchHistoryService->getLastWatchedRedirectUrl(
    request()->route('lang') ?? 'en'
);

if ($redirectUrl) {
    // Set the intended URL so Laravel's redirectIntended() will use it
    session(['url.intended' => $redirectUrl]);
    
    Log::info('Magic link redirect URL set as intended', [
        'user_id' => $user->id,
        'redirect_url' => $redirectUrl
    ]);
}
```

### 2. Redirect Logic (ChooseLanguage.php)
```php
public function mount(): void
{
    $this->languages = MeloloService::$languages;
    
    // Check if user is logged in and has an intended redirect URL
    if (Auth::check()) {
        $intendedUrl = session('url.intended');
        if ($intendedUrl) {
            // Clear the intended URL and redirect
            session()->forget('url.intended');
            $this->redirect($intendedUrl, navigate: true);
            return;
        }
        
        // Default redirect to English home page for logged-in users
        $this->redirect('/en', navigate: true);
    }
}
```

## Flow
1. User clicks magic link → `SetEmailVerifiedOnMagicLinkLogin` processes login and sets `session(['url.intended' => $lastWatchedUrl])`
2. Magic link redirects to `/` → `ChooseLanguage` component loads
3. `ChooseLanguage` detects authenticated user + intended URL → redirects to last watched episode
4. User lands on their last watched episode page

## Benefits
- ✅ **Seamless UX**: Users go directly to their last watched content
- ✅ **Laravel Standard**: Uses Laravel's built-in intended URL mechanism
- ✅ **Clean Code**: Minimal changes to existing codebase
- ✅ **Fallback Safe**: Still works if no redirect URL available

## Testing
Run `php artisan drama:test-magic-link-transfer` to verify functionality:
```bash
✅ Redirect URL generated successfully: http://dracin.test/in/drama/7559781493317307409/episode/3
✅ Set intended URL in session: http://dracin.test/in/drama/7559781493317307409/episode/3
✅ Retrieved and cleared intended URL: http://dracin.test/in/drama/7559781493317307409/episode/3
✅ Magic link redirect flow working correctly
