The execCommand fallback returned true but copied nothing because the textarea
was readOnly=false. iOS only copies from a readOnly + contentEditable field with
a real Range selection + setSelectionRange — fixed that. Also skip the async
Clipboard API unless window.isSecureContext (on the plain-HTTP LAN PWA it could
resolve without copying, showing a false checkmark). If programmatic copy still
fails, fall back to a prompt() with the text so it can be copied by hand, and only
show the ✓ on real success.
