feat(editor): add file upload and fix critical bugs

- Add markdown file upload functionality with upload button
- Fix error handling to throw errors instead of silently returning empty strings
- Fix memory leak by cleaning up debounceTimer in onUnmounted
- Update debounce timing from 150ms to 500ms for stability
- Enhance UI with floating action buttons and extensive style refinements
- Hide toolbar, menu, and line number elements for cleaner interface
