Description

This PR completes the Reviews card task by adding the following:

1. Updates loading behavior to:
   1. prefer fetching local review data first and show it, if available,
   2. show partial review data if fetched data becomes available even before fetching product name or notifications
2. Finalizing UI for loading state,
3. UI for error state,
4. UI for empty state (both for when there's no reviews at all in the site, and when there's no reviews after filtering)
5. Trackings

Testing instructions

Screenshots

Error case:

Empty state case: absolutely no reviews	Empty state case: no filtered reviews

• I have considered if this change warrants user-facing release notes and have added them to RELEASE-NOTES.txt if necessary.
