fix(path): return empty string from getReadablePath when path is empty

ROO-437: Prevent showing CWD basename when file path is empty/undefined

When getReadablePath() was called with an empty or undefined path, it
returned path.basename(cwd) (e.g., 'extracker'), which was misleading
users into thinking the model was trying to write to a directory.

Now it returns an empty string instead, so the UI shows nothing rather
than a misleading directory name when the path is unavailable.
