Replace manual BackButton management with official @telegram-apps/react-router-integration
to fix navigation issues (back button cycling and double-click).
Changes:
- Migrate from @tma.js/sdk-react to @telegram-apps/sdk-react
- Downgrade react-router-dom to v6 for package compatibility
- Add AppWithNavigator component with Telegram navigator integration
- Use browser history mode (hashMode: null) to prevent hash URLs
- Add multi-level platform detection (user data, platform, version)
- Add try-catch error handling for navigator attach/detach
- Simplify useBackButton hook to no-op (navigator handles automatically)
- Update vite config with new Telegram packages
The navigator automatically manages BackButton based on router history,
falling back to BrowserRouter in regular browser environment.
- Removed VITE_APP_VERSION from Dockerfile and GitHub workflows.
- Simplified Vite configuration by eliminating the Git version retrieval function and global constant for app version.
- Updated ColorPicker and other components to enhance accessibility with aria-labels.
- Introduced unique identifiers for buttons in the AppEditorModal for better React key management.
- Improved error handling in the Login component to provide user-friendly messages without exposing sensitive data.
- Introduced VITE_APP_VERSION in Dockerfile and GitHub workflows to capture the version from Git tags.
- Updated vite.config.ts to define a global constant for the app version.
- Enhanced Layout component to display the app version in the footer for admin pages.
- Added logic to conditionally render the LanguageSwitcher based on active promotions.
