WIP (fix): improve electron build configuration and service worker handling

- Properly disable service workers in electron builds
- Add CSP headers for electron security
- Fix path resolution in electron context
- Improve preload script error handling and IPC setup
- Update build scripts for better electron/capacitor compatibility
- Fix router path handling in electron context
- Remove electron-builder dependency
- Streamline build process and output structure

This change improves the stability and security of electron builds while
maintaining PWA functionality in web builds. Service workers are now
properly disabled in electron context, and path resolution issues are
fixed.
