fix: preserve optional login behavior for V-001

Replace throw-on-missing credential pattern with direct env var reads
so undefined cleanly represents "not configured" instead of crashing
the app at startup when muserId/mtoken are absent. Update downstream
guards in androidURL.js and updateData.js to truthy checks that handle
both undefined and empty string.
