Use coins_plm.py as single source of truth for ElectrumX patch

- Remove inline Palladium coin definition from Dockerfile.electrumx
  and COPY coins_plm.py instead, reducing duplication
- Add TX_COUNT/TX_COUNT_HEIGHT/TX_PER_BLOCK to coins_plm.py with
  real chain data (457478 txs at height 382404)
- Update entrypoint.sh to fetch live TX stats from palladiumd at
  container startup, keeping sync estimates accurate automatically
