refactor: enhance error handling and theming in EnhancedErrorService

- Updated the EnhancedErrorService to utilize the dynamic theme context for improved color handling in SnackBars and AlertDialogs.
- Replaced hardcoded color values with theme-based colors to ensure better accessibility and visual consistency across the application.
- Added context parameter to various components to facilitate theme integration, enhancing the overall user experience.
- Improved the readability of error messages by applying appropriate text colors based on the current theme.
