fix(ui): register trigger and sensor graph node types

[windro-xdd]

Summary

• Register missing trigger and sensor node type mappings in UI graph nodeTypes to avoid render failures when those node kinds appear in dependency graphs
• Add focused unit test coverage for the new node type registrations
• Keep scope intentionally minimal (no i18n or unrelated file changes)

Testing

• pnpm test src/components/Graph/graphTypes.test.ts
• pnpm test src/components/Graph
• pnpm lint
• pnpm build

Screenshot

Screenshot added - DAG graph view showing proper rendering of trigger and sensor nodes with the fix applied. See comments below for details.

Supersedes #64689.

Closes #64621
Closes #49576

Screenshot (trigger + sensor nodes rendering)

Added screenshot to this PR branch:

airflow-core/src/airflow/ui/src/components/Graph/trigger-sensor-graph-screenshot.png

Preview:

What this shows:

• wait_sensor rendered as TimeDeltaSensor
• trigger_next rendered as TriggerDagRunOperator
• Graph view renders both node kinds without blanking/crashing

We only need this file

Thanks for the review and for calling out the scope.

I cleaned this PR so it only includes graphTypes.ts now.

• Removed graphTypes.test.ts
• Removed the committed screenshot file

The screenshot context came from the earlier closed PR discussion (#64689), where a screenshot had been requested. I kept that context in comments only, but removed non-essential files from this PR so the diff stays focused on the single file fix.

Great. Thanks for working on this and for graciously responding to the reviews in your previous PR.

Thanks again for the review and guidance. I’m still getting used to the project workflow, and I really appreciate the patience and feedback.
