docs(audiobookshelf): the probe routes answer at the root under either base path

Measured on both shapes: ping returns success:true and healthcheck returns OK at the root whether or not the app is mounted under a prefix, which is why the phone app's connectivity check works before it ever resolves the base path. The paragraph now says which routes were probed instead of asserting 200s in general, and the frontmatter description fits the OKF 120-char budget the linter enforces.
