- 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
Add PalladiumTestnet class with testnet-specific configurations including ports, address prefixes, and genesis hash. Update docker-compose.yml with clear network configuration comments and documentation in README.md explaining how to switch between mainnet and testnet.
