TekH e5402bafc9 Refactor and cleanup EnvelopeSender components
Refactored code for improved readability, consistency, and maintainability. Removed the WASM boot loading overlay and its associated styles/scripts. Updated SVG paths to use self-closing tags for HTML compliance. Reformatted conditional blocks, state management, and session data logic. Enhanced error handling, spinner visibility, and empty state displays.

Removed redundant comments and unused code. Added `envelope-editor.js` for new functionality. Cleaned up CSS and JavaScript related to the removed WASM overlay. Improved grid layout persistence and signature field logic. Adjusted localization strings for better alignment with German translations.
