fix: bundle the Electron preload so the sandboxed bridge loads in packaged builds (v2.0.1)

The preload script imported ../shared/ipc at runtime; sandboxed preloads cannot
require local modules, so window.eveflow was never exposed in the installed app
and every request fell back to browser fetch (Failed to fetch, LOCALHOST metrics).
Main and preload are now bundled with esbuild into single files in dist-electron/.

Also: explicit error banner when the bridge is missing inside Electron, and a more
precise connection test message (transport path, capabilities status).
