fix(ui): prevent Launch LoRA Manager button from disappearing when opening properties panel in subgraph (#996)

In Vue render mode, ComfyUI's TransformPane uses a capture-phase wheel
handler (@wheel.capture) that fires before the tag element's bubble-phase
strength-adjustment listener. It checks wheelCapturedByFocusedElement(),
which requires data-capture-wheel on a focused element. The tag divs had
data-capture-wheel but were not focusable, so the check failed, causing
the capture handler to forward the event to the canvas (triggering zoom)
and stopPropagation() which prevented the strength handler from running.

Fix: move data-capture-wheel from individual tags to the container, make
it focusable (tabIndex=-1), and add a window-level capture-phase wheel
listener that focuses the container before TransformPane checks it.
