Subject: [PATCH] feat(desktop): bridge MAIN_VITE_API_URL to process.env for
 packaged builds

In packaged Electron builds, @multica/core is externalized and .env
files are excluded. Bridge import.meta.env.MAIN_VITE_API_URL (injected
at build time by electron-vite) to process.env.MULTICA_API_URL so that
getApiBaseUrl() reads the correct value in staging/test environments.
