fix(desktop-main): lazy-load electron-store to avoid requiring electron binary in tests

electron-store v11 imports electron at the top of its index.js, so any
require('electron-store') fails in plain-Node environments where the
electron binary hasn't been downloaded (e.g. integration test CI).

Switch the import to `import type` (type-only, no runtime effect) and
use createRequire inside createStore(), which is only called when
readIsElectron() returns true. Plain-Node paths continue to use the
in-memory Map fallback without ever loading electron-store.
