Duplicate track keys in `DaffTreeComponent`

[xelaint]

Is this a regression?

• [ ] Yes, this behavior used to work in the previous version

Description

Duplicate track keys in DaffTreeComponent.

The provided track expression resulted in duplicated keys for a given collection. Adjust the tracking expression such that it uniquely identifies all the items in the collection.

trackByTreeElement is resulting in duplicated keys. Using el.title might not be the best since there could be duplicate titles (e.g. Overview)

Environment

• Daffodil version: 0.90
• Angular version: 20
• Browser(s):
• Node version: run node --version
• Operating system:

Steps to reproduce

Steps to reproduce:

1. Run a watch on design (npx nx run @daffodil/design:build --watch)
2. Run serve npx ng s daffio
3. Convert *ngFor="let node of flatTree; trackBy: trackByTreeElement" to @for expression
4. See in console the warnings

Expected behavior

trackByTreeElement should result in all unique keys

Actual behavior

The provided track expression resulted in duplicated keys for a given collection. Adjust the tracking expression such that it uniquely identifies all the items in the collection.

@damienwebdev @griest024 @F4tal1t Seems like the update in #4115 did not fix this issue. I'm still seeing the warning in console in my local environment.

hm, node.id should be unique right?

@griest024 I'm seeing it in design-land. Not sure if it a tree component issue or design-land implementation issue.
