/**
 * Unit tests for path prefix injection in UI rendering.
 *
 * Verifies that when pathPrefix is set (e.g., '/git'), all rendered
 * HTML correctly uses the prefix in links, buttons, and script vars.
 * Without this, deploying behind a reverse proxy (e.g., 7rnx.net/git/)
 * breaks all navigation.
