allow Vue nodes to be resized from all 4 corners (#6187)

## Summary

Enables Vue nodes to resize from all four corners and consolidated the
interaction pipeline.

## Changes

- **What**: Added four-corner handles to `LGraphNode`, wired them
through the refactored `useNodeResize` composable, and centralized the
math/preset helpers under `interactions/resize/` with cleaner pure
functions and lint-compliant markup.

## Review Focus

Corner-to-corner resizing accuracy (position + size), pinned-node guard
preventing resize start, and snap-to-grid behavior at varied zoom
levels.
