Reader: Migrate useReadFeedSiteQuery to api-core/api-queries

[gabrielcaires]

Part of READ-410

Proposed Changes

• Extract pure fetcher function (fetchReadFeedSite) into packages/api-core/src/read-sites/
• Create readFeedSiteQuery() query options wrapper in packages/api-queries/src/read-site.ts
• Replace direct wpcom-proxy-request call with the centralized wpcom fetcher
• Update consumers (reader-feed-item, customer-council-banner) to import from the new location
• Remove old useReadFeedSiteQuery hook from packages/data-stores/src/reader/

Why are these changes being made?

• This migrates the /read/sites/{id} query to the standardized api-core / api-queries pattern, aligning with the ongoing effort to move queries out of Redux/data-stores into React Query with centralized fetchers.

Testing Instructions

• Verify the Reader feed item component still loads site info correctly (icon, description, URL) for WPCOM feeds in the subscriptions search results.
• Verify the Customer Council banner in the Reader stream still checks subscription status correctly.

packages/api-core/src/index.ts currently exports ./products twice (two identical export * from './products'; lines). Since this PR is already touching the barrel in this area (adding ./read-sites), it’s a good opportunity to drop the duplicate export to keep the entrypoint clean and avoid confusion about where exports come from.

Suggested change

export * from './products';
