Filter GPP notices from TCF experience options

[gilluminate]

Ticket ENG-1237

Description Of Changes

Added validation and UI improvements to prevent GPP notices from being configured in TCF experiences. When GPP notices are detected in a TCF experience, an error alert is displayed. The privacy notice dropdown now filters out GPP notices for TCF experiences and shows a disabled placeholder option to inform users that GPP notices are not supported.

Code Changes

• Filtered GPP notices from the available options when configuring TCF experiences
• Added error alert when existing GPP notices are detected in TCF experience configuration
• Added disabled placeholder option in dropdown to inform users GPP notices are not supported in TCF
• Enhanced ScrollableList component to support disabled items via isItemDisabled prop
• Updated dropdown to use variable width (popupMatchSelectWidth={false}) to display longer option names without ellipsis
• Added search functionality to dropdown with optionFilterProp="label"

Steps to Confirm

1. Navigate to a TCF experience configuration
2. Verify that GPP notices are filtered from the privacy notice dropdown
3. Verify that a disabled "GPP notices not supported in TCF" option appears in the dropdown if any GPP notices exist
4. If a TCF experience has existing GPP notices configured, verify an error alert is displayed
5. Verify that non-TCF experiences still show all privacy notices including GPP notices

Greptile Overview

Greptile Summary

This PR adds validation to prevent GPP (Global Privacy Platform) notices from being configured in TCF (Transparency and Consent Framework) experiences, improving data integrity for consent management.

Key Changes:

• GPP notices (gpp_us_national and gpp_us_state frameworks) are now filtered from the privacy notice dropdown when configuring TCF experiences
• An error alert displays when existing GPP notices are detected in TCF configurations
• A disabled "GPP notices not supported in TCF" placeholder option appears in the dropdown to inform users
• Enhanced ScrollableList component with isItemDisabled prop for better disabled item handling
• Added search functionality (optionFilterProp="label") and variable width popup (popupMatchSelectWidth={false}) to the dropdown for improved UX
• Comprehensive Cypress tests validate the filtering behavior and error messaging

Issues Found:

• When switching from another experience type to TCF Overlay, line 329 replaces all existing privacy notices with just the TCF placeholder, causing users to lose their previously selected non-GPP notices

Confidence Score: 4/5

• Safe to merge with one logical issue that causes data loss when switching to TCF experience type
• The filtering logic and UI enhancements work correctly, but switching to TCF_OVERLAY discards existing valid notices instead of preserving non-GPP ones
• PrivacyExperienceForm.tsx line 329 needs attention for the component change handler logic

When switching to TCF_OVERLAY, existing privacy notices are being replaced entirely with just the placeholder. Users lose their previously selected notices.

Consider preserving existing non-GPP notices:

      updates.privacy_notice_ids = [
        TCF_PLACEHOLDER_ID,
        ...(values.privacy_notice_ids?.filter(
          (id) => {
            const notice = allPrivacyNotices.find((n) => n.id === id);
            return notice && !isGppNotice(notice);
          }
        ) ?? []),
      ];
