Migrate node graph UI interaction from frontend to backend (#1768)

* Click node using click targets based

* Display graph transform based on state stored in Rust, fix zoom and pan.

* Migrate node selection logic

* Move click targets and transform to NodeNetwork

* Keep click targets in sync with changes to node shape

* Click targets for import/export, add dragging

* Basic wire dragging

* complete wire dragging

* Add node selection box when dragging

* Fix zoom operations and dragging nodes

* Remove click targets from serialized data, fix EnterNestedNetwork

* WIP: Auto connect node when dragged on wire

* Finish auto connect node when dragged on wire

* Add context menus

* Improve layer width calculations and state

* Improve context menu state, various other improvements

* Close menu on escape

* Cleanup Graph.svelte

* Fix lock/hide tool tip shortcuts

* Clean up editor_api.rs, fix lock/hide layers

* Start transferring network and node metadata from NodeNetwork to the editor

* Transfer click targets to NodeGraphMessageHandler

* Fix infinite canvas

* Fix undo/redo, scrollbars, and fix warnings

* Unicode-3.0 license and code cleanup

* License fix

* formatting issue

* Enable DomRect

* Fix layer move crash

* Remove tests

* Ignore test

* formatting

* remove white dot
