fix(genui): remove duplicate 'component' in required list in prompt

- Use a `Set` to avoid duplicate entries when generating the `required` list for components in the catalog schema.
- Update golden files to reflect the fix.
- Add mock asset handler to `travel_app` tests to fix failing test.

Follow-up for #873.
