…ipboard fails
On the web interface, navigator.clipboard.writeText() can silently fail in
non-HTTPS contexts (localhost) or when the Clipboard API is blocked. Added a
writeClipboard() helper that falls back to document.execCommand('copy') via a
temporary textarea, which works in all browser contexts. Also gate the 'copied'
state update on the actual copy result.
Fixes anomalyco#27992
