update DynamicJsonForm tests; add enum coverage and JSON-mode assertions

- Align tests with new form-first rendering and UI behavior:
  - Labels prefer schema `title` over property key.
  - Descriptions shown for boolean checkboxes and select fields.
  - Explicit mode switching between Form/JSON when needed.
- Add comprehensive coverage for enum schema variants:
  - Titled single-select via `oneOf`/`anyOf` with `{ const, title }`.
  - Untitled single-select via `enum` (with legacy `enumNames` labels).
  - Untitled multi-select via `items.enum` with `minItems`/`maxItems` helper text.
  - Titled multi-select via `items.anyOf`/`oneOf` with `{ const, title }`.
- Adjust complex/JSON-mode tests to click “Switch to JSON” before asserting textarea and clipboard interactions.
- Fix debounced JSON update expectations to assert parsed objects rather than raw text.
