+/**
+ * Tests for ConfigPage (M2-T08).
+ *
+ * Strategy: vi.mock the apiClient module so we can control GET/PUT/POST responses
+ * without a real server.
+ *
+ * Coverage:
+ * 1. Renders config sections from a mocked GET /api/config response.
+ * 2. Secret fields start as empty (never display masked value).
+ * 3. Non-secret fields show their loaded values.
+ * 4. Save: updates map includes all non-secret fields and excludes untouched secrets.
+ * 5. Save: updates map includes a secret only when the user typed a new value.
+ * 6. Save success → shows success notice.
+ * 7. Save error → shows error notice.
+ * 8. SMTP test button: success state (200 result=success).
+ * 9. SMTP test button: config-error state (400/ApiError result=config-error).
+ * 10. SMTP test button: failed state (502/ApiError result=failed).

- * T08 replaces this with the real config UI: all config sections rendered as editable
- * fields, secret masking, save button (PUT /api/config), and SMTP test action.
+ * Behaviours:
+ * 1. Load config: GET /api/config → render sections (grouped) with Mantine inputs.
+ *    - Non-secret fields show their value.
+ *    - Secret fields render as empty PasswordInput (never show a masked value).
+ * 2. Save config: PUT /api/config with full-field submission semantics.
+ *    - All non-secret fields are ALWAYS included (to avoid backend zeroing absent fields).
+ *    - Secret fields are included ONLY when the user typed a new (non-empty) value.
+ *    - On success: show a success notice and refetch config.
+ *    - On ApiError 422: show an error notice, nothing was written.
+ * 3. SMTP test button: POST /api/config/smtp/test.
+ *    - Tri-state: success / config-error / failed.
+ *    - Errors read `err.body.result` from ApiError.
