Pull request overview
This PR introduces a new backend-driven contract storage data source (with a health-check gate) and falls back to StellarExpert when the backend is not healthy, aligning contract explorer storage retrieval with the project’s own backend API.
Changes:
- Added backend health-check and backend contract-storage query hooks.
- Updated contract explorer UI to choose backend vs StellarExpert for contract storage based on backend health.
- Updated network limit constants and introduced backend storage response typing + production env var.

Works great! I think we can try to tweak TanStack Query to keep the previous data until the new data is loaded. Right now, we show loader when switching to a new page or using sort features, which makes the page content jump around.
Also, when going back to a page that I just fetched, we shouldn't need to fetch it again. This is also something we can control in TanStack Query.
