feat(studio): suggest starter tests on the empty Test and Validate tab (ASTD-498)

[aray12]

Summary

Add two one-click "Add Test" suggestions (PII, Jailbreak) below "Add Another Test" when a guardrail config has no test cases yet, seeded with hardcoded content matched to SELF_CHECK_INPUT_PROMPT's policy bullets. Each fires the same create-check mutation "Add Another Test" already uses.

Changes

• New suggestedTestCases.ts with the two suggestion definitions (label, icon, content).
• GuardrailTestCasesEditor.tsx: render the suggestion cards, gated on the tab having zero checks; each card has an inline "Add Test" button.
• Test coverage for showing/hiding the suggestions and creating a check from one.

Make exported suggestion definitions immutable.

Consumers can mutate IDs or content and change the rendered and persisted tests. Mark the fields and array as readonly.

Proposed fix

 export interface SuggestedTestCase {
-  id: string;
+  readonly id: string;
-  label: string;
+  readonly label: string;
-  icon: LucideIcon;
+  readonly icon: LucideIcon;
-  content: string;
+  readonly content: string;
 }
 
-export const SUGGESTED_TEST_CASES: SuggestedTestCase[] = [
+export const SUGGESTED_TEST_CASES: readonly SuggestedTestCase[] = [

As per coding guidelines, use readonly for immutable properties.
