feat(electron): bundle worker assets and resolve worker path

Add webpack config and include it in the electron backend build so 
worker scripts are correctly bundled for packaged apps. Move worker 
files to be packaged as extraResources instead of asar unpack patterns 
so the packaged app can load worker JS from Resources/dist/... at 
runtime. Fix worker path resolution in epg.events: compute resourcesPath
from app.getAppPath() and point to dist/apps/electron-backend/workers 
when app.isPackaged. Remove verbose app path logging and update comments
to reflect the actual packaged layout.
Why: ensure webworker entry points are included in the renderer/backend
bundle and accessible when the Electron app is packaged, preventing
worker loading failures in production builds.
