FN-6366: fix desktop Vitest constructor mocks
Stabilize the desktop Vitest suite under Vitest 4.1.8 while keeping dashboard builds complete.
- Convert Electron constructor mocks to constructable function implementations for BrowserWindow, Tray, Notification, and LocalRuntimeManager.\n- Assert local runtime initialization uses the mocked home directory in desktop main-process tests.\n- Build dashboard runtime plugin packages before the desktop dashboard build.
