migrate home app ui tests to scout (#271356)

## Summary

Migrates the `home/feature_controls` FTR suite to Scout, splitting the
assertions across the layer that owns each contract:

- Scout UI
(`src/platform/plugins/shared/home/test/scout/ui/tests/feature_controls.spec.ts`):
1 parametrized spec, 2 roles. Asserts the visible solution panels and
the Manage section / Stack Management quick-link on the Home page — the
wiring between capabilities, the feature catalogue and the rendered DOM.
- Existing Jest (`manage_data.test.tsx`): already locks the
component-level contract (section/button visibility given a navLinks
shape) — left as-is, no new unit test needed.

Custom roles live once in `test/scout/common/custom_roles.ts`

### Test coverage parity
Every assertion from the deleted FTR is still covered:

- Solutions list per role → Scout UI
- homeDataManage section visibility per role → Scout UI + existing Jest
- homeManage button visibility per role → Scout UI + existing Jest
