fix: remove features string from window.open to enable tab reuse

window.open(url, name, 'noopener,noreferrer') with a non-empty features
string forces a new popup window and ignores the name for tab reuse.
Remove the third parameter so the browser focuses existing named tabs.

Quality gates: tsc --noEmit pass, npm run build pass, 80/80 tests pass
