fix(cron): "Script not found" says scripts are per-profile and how to fix it

Cron scripts resolve only against the job's own profile scripts/ dir (by design,
profiles never share files), so a job copied between profiles fails with a path
that looks plausible and no hint about why. The runtime error now names the
profile folder and the two fixes (copy the script, or `hermes cron edit`).

Closes #94821. Builds on #105775 (creation-time existence check, credited).
