fix(canvas/Toolbar): help button always opens — no double-click close bug

The help button's onClick used setHelpOpen((open) => !open) (toggle).
Combined with the window.pointerdown handler that closes on outside-click,
clicking outside then clicking the help button would: pointerdown outside
(close) → click on button (!false = true → open) → pointerdown ON button
(contains=true, no close) → BUT the next interaction would have stale
toggle state causing a double-close on the following click.

Fix: button onClick always calls setHelpOpen(true) — the pointerdown
outside handler owns the close path; the button only opens.

Also add 2 tests: pointer-down-outside closes, and re-open works after
outside click (regression for the double-click bug).

-// causing retry storms and "error" rendering in canvas despite the response being available.
