Refactor Dockerfile and Vite configuration to remove VITE_APP_VERSION and streamline build process

- 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.
