Cursor Agent 6b59750621 feat: add detailed error display widget for debugging
Problem:
- Gray screens without error messages made debugging impossible
- Users couldn't see what went wrong
- Developers couldn't debug issues without full stack traces

Solution:

1. Created ErrorDisplay widget (lib/presentation/widgets/error_display.dart):
    Shows detailed error message with copy button
    Expandable stack trace section with syntax highlighting
    Retry button for failed operations
    Debug tips for troubleshooting
    Beautiful UI with icons, colors, and proper styling
    Fully selectable text for easy copying

   Features:
   - 🔴 Red error card with full error message
   - 🟠 Orange expandable stack trace panel
   - 🔵 Blue tips panel with debugging suggestions
   - 📋 Copy buttons for error and stack trace
   - 🔄 Retry button to attempt operation again
   - 📱 Responsive scrolling for long errors

2. Updated MovieDetailProvider:
    Added _stackTrace field to store full stack trace
    Save stack trace in catch block: catch (e, stackTrace)
    Expose via getter: String? get stackTrace

3. Updated DownloadsProvider:
    Added _stackTrace field
    Updated _setError() to accept optional stackTrace parameter
    Save stack trace in refreshDownloads() catch block
    Print error and stack trace to console

4. Updated MovieDetailScreen:
    Replaced simple Text('Error: ...') with ErrorDisplay widget
    Shows 'Ошибка загрузки фильма/сериала' title
    Pass error, stackTrace, and onRetry callback
    Retry attempts to reload media

5. Updated DownloadsScreen:
    Replaced custom error UI with ErrorDisplay widget
    Shows 'Ошибка загрузки торрентов' title
    Pass error, stackTrace, and onRetry callback
    Retry attempts to refresh downloads

Error Display Features:
