Updates to privacy notice sandbox

Description Of Changes

We recently made some changes to the consent v3 API, so we need to update the privacy notice sandbox accordingly. The API override_mode query param changed to policy . Old name -> new name:

• descendants -> cascade_down
• ancestors -> cascade_up
• all -> cascade_up_and_down

This PR also removes a lot of the complex cascading logic the UI had and delegates it all to the backend; no cascading will be done in the privacy notice checkbox tree, but rather the tree is reloaded from the backend response after preferences are saved. It also removes the "simulated data" tab as that has fallen behind and is no longer needed now that we have a working API.

Code Changes

• Update override_mode to policy
• Remove complicated cascading logic from the UI
• Add a property_id input to allow retrieving an experience configured on a specific property
• Remove Simulated data tab and related components

Greptile Overview

Greptile Summary

This PR updates the privacy notice sandbox to align with recent Consent V3 API changes, replacing the override_mode query parameter with policy and updating the enum values (descendants → cascade_down, ancestors → cascade_up, all → cascade_up_and_down).

Key changes:

• Removed ~100 lines of complex client-side cascading logic from PrivacyNoticesTree.tsx - the tree now only tracks explicit user changes and delegates all cascading behavior to the backend
• After saving preferences, the UI reloads the tree state from the backend response to reflect server-side cascading
• Removed the "Simulated data" tab and ~70 lines of hardcoded mock data constants, simplifying the sandbox to only use real API calls
• Added property_id input field to allow testing experiences configured on specific properties
• Fixed timestamp format in collected_at metadata (now uses +00:00 instead of Z suffix)

Confidence Score: 5/5

• This PR is safe to merge - it's a well-executed refactoring that simplifies the codebase by removing complex client-side logic
• The changes are clean and focused: removing 873 lines while adding only 205 lines demonstrates effective simplification. The PR delegates cascading logic to the backend (eliminating client-side complexity), updates API parameters to match backend changes, and removes unused mock data. The code is more maintainable and follows proper separation of concerns. This is sandbox/testing code with limited production impact.
• No files require special attention - all changes are straightforward refactoring and API updates

It doesn't look like parentMap is being used for anything anymore.

[erosselli]

ah you're right, will remove. thanks!

[gilluminate]

a couple of nit-picks, but otherwise looking good.
