Implement Node Manager

[camielvs]

Description

Replace all task/input/output -> node id conversions with the new NodeManager. In other words, the nodeIdUtils file has been replaced with the new NodeManager.

i.e. replace all instances of inputNameToNodeId, outputNameToNodeId, and taskIdToNodeId (and the reverse operations) with the NodeManager's getNodeId and getRefId methods (or getInputNodeId and getOutputNodeId via the useNodeManager hook). This also includes replacement of all methods dealing with Handle ids as well, and these have been brought into the node manager via getHandleNodeId and getHandleInfo.

inputNameToNodeId --> getInputNodeId
outputNameToNodeId --> getOutputNodeId
taskIdToNodeId --> getTaskNodeId

All nodes & handles will now have a uniquely assigned node id for use in ReactFlow and via the NodeManager this is mapped back to their respective id in the component spec. For handles they are mapped to the parent object they are one.

Also includes a few minor refactors such as removeEdge, to make things more human-readable.

Includes some AI-generated updates to tests.

Closes Shopify/oasis-frontend#261

Type of Change

• Cleanup/Refactor
• Improvement

Checklist

• I have tested this does not break current pipelines / runs functionality
• I have tested the changes on staging

Test Instructions

1. Check that new & existing pipelines continue to function as expected with the updated node ID management

• can add tasks and IO nodes
• can connect stuff
• can copy stuff
• can export, import, edit
• can execute pipelines
  etc

2. You can use DEBUG_MODE to see if node ids are generating and updating uniquely
