/**
 * Unit tests for `dashboard-paths.ts` helpers.
 *
 * Pins each getter accepts a `{ homedir }` override and falls back to
 * `os.homedir()` when none is provided. Asserts that the live server
 * log path and the legacy installer log path resolve to *distinct*
 * files even though both end in `server.log`.
 *
 * See change: harvest-bootstrap-survivor-fixes (cherry-pick 1).
