[chronik] Add blocktxs_and_tx_and_rawtx.rs integration test to bitcoinsuite-chronik-client

Summary:
Tests verify transaction and block retrieval from the Chronik client. They check:

• Block and transaction retrieval by height and hash
• Transaction validation in mempool and after mining
• Raw transaction data verification
• Pagination of block transactions with custom page sizes
• Error handling for non-existent or invalidated blocks/transactions
• Proper handling of coinbase transactions

This ensures the Chronik client correctly handles transaction queries and blockchain state changes.

Test Plan:
Please set BUILD_DIR env to export BUILD_DIR="/path/to/build_dir
UNIX: ./contrib/teamcity/build-configurations.py build-bitcoinsuite-chronik-client
