Unhide Properties panel (#6652)

This pull request makes a minor UI adjustment to the node settings panel
in the `LGraphCanvas` class. The panel's position is now set to
absolute, with specific top and left offsets to improve its placement on
the canvas.

* Set the `panel` element's CSS `position` to `absolute` and specified
`top` and `left` values for better UI alignment in `LGraphCanvas.ts`.
