[ui] Replace dagre GitHub fork with npm package + Yarn patch (#21613)

## Summary & Motivation

The objective of this PR is to clean up the logspew that shows up in CI when we yarn install the dagre fork.

This PR applies a patch to the `dagre` npm package to fix graph layout issues and add cluster padding configuration options, instead of the current approach of targeting a fork.

## Test Plan

Verify with BK inspection that we're no longer spewing logs and warnings on the yarn install step.

- Verify that graph layouts render without crashing when encountering null nodes
- Test that the new cluster padding attributes are properly applied to graph layouts
- Ensure existing graph functionality remains unchanged
