Enhance entry deletion process: ensure immediate file save after deletion and restore entry on save failure for improved reliability.

- Deleted the main entry point file for the hosts application.
- Updated the Add Entry Modal to improve section titles and input styles.
- Refactored HostsManagerApp layout to use common pane styles for left and right sections.
- Enhanced Config, Delete Confirmation, and Help modals with consistent button labels and styles.
- Improved Password Modal layout and removed unnecessary parameters.
- Consolidated common CSS styles for buttons, inputs, and sections to ensure consistent styling across the application.
