Subject: [PATCH] Fix persistent 429: bust JS cache, stagger all API calls
 sequentially

- Add ?v=2 cache busting to all JS script tags (old version was cached)
- Reduce nginx JS cache from 1y to 1h with must-revalidate
- fetchChainData now sequential (was 4 parallel requests per chain)
- Increase chain detection delay from 150ms to 300ms
