fix bypass hotkey in vue nodes and fix node data instrumentation setup issue when switching to Vue nodes after initial load (#5715)

## Summary

Fixed Vue node keybinding target element ID to enable
bypass/pin/collapse hotkeys in both LiteGraph and Vue rendering modes.

Also fixed a bug when starting in litegraph mode => switching to Vue
nodes without reloading => `graph.onTrigger` is set to `undefined` which
interferes with proper setup of node data instrumentation, among other
things.

## Changes

- **What**: Updated keybinding `targetElementId` from `graph-canvas` to
`graph-canvas-container` for node manipulation commands (parent of both
the canvas and transform pane -- vue nodes container).
- **What**: Added conditional `onTrigger` handler restoration in slot
layout sync to prevent Vue node manager conflicts

## Review Focus

Event handler precedence between Vue nodes and LiteGraph systems during
mode switching, ensuring hotkeys work consistently across rendering
modes.
