fix: use regex matching in patch script + add geoblock IP check

Browse Source 
- Rewrite patch-clob-client.cjs to use regex instead of exact string
  matching, so it works regardless of code formatting differences
  between npm versions (fixes "Could not find request config line" on
  fresh VPS install)
- Add multiple fallback patterns (config regex → fallback regex →
  axios call injection) with debug output if all fail
- Add Polymarket geoblock API check (polymarket.com/api/geoblock)
  for both VPS direct IP and proxy IP at startup
