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
