Subject: fix(tooltip): remove body-appended tooltip node on destroy

LinkedTooltip appends its tooltip div directly to document.body in
createTooltip and only removes it from hideTooltip. If the component
was destroyed while the tooltip was visible (e.g. parent navigated
mid-hover), the div leaked and stayed in the DOM forever.

Add an onDestroy handler that clears the pending hide/debounce timers
and, if the tooltip div is still parented to document.body, removes
it. Guarding on parentNode avoids double-removal when hideTooltip has
already run.
