SnapOtter 7a3b4e6b3b fix(security): basename-sanitize file-preview paths (CodeQL js/path-injection)
The resolve()+startsWith containment check was correct but CodeQL did not
recognize it. Apply path.basename() to the name in resolveWithinPreviewDir -- a
sanitizer CodeQL recognizes -- so every id-derived preview path is provably a
single filename inside the preview dir. Behaviour is unchanged for valid ids
(already charset-validated); containment check kept as a backstop.
