ZDDC defed434cc feat(form): pre-flight Submit gate + cap-toast on 403
Two changes to the form tool's submit path:

  - Submit button hides when /.profile/access?path=<submission dir>
    reports no 'c' verb. The form-status line surfaces a short
    explanation so the user knows why the button disappeared.
  - 403 on POST routes through zddc.cap.handleForbidden, which
    renders an error toast naming the missing verb and offers
    Elevate when the path-scoped view reports an elevation grant
    covering it. The existing "You are not allowed to submit here"
    status line still appears as the in-form indicator.

Also guards shared/cap.js's fetchAccess against file:// URLs —
calling fetch() on a file:// page logs a browser-level error that
shows up as test-runner noise. Short-circuiting to null lets
offline tools (browse on a picked folder, form opened standalone
from a file URL) silently degrade to "no path-scoped info" and
fall back to whatever existing gate they had.
