feat: wire systemd services to use centralized aitbc package

- Create wrapper scripts for all AITBC services using aitbc utilities
- Update 13 systemd service files to use wrapper scripts
- Wrapper scripts use aitbc constants (ENV_FILE, NODE_ENV_FILE, DATA_DIR, LOG_DIR, KEYSTORE_DIR)
- Services migrated: agent-coordinator, agent-daemon, agent-registry, blockchain-event-bridge, blockchain-node, blockchain-p2p, blockchain-rpc, blockchain-sync, coordinator-api, explorer, marketplace, wallet
- Add sys.path setup to cli/aitbc_cli.py for aitbc package access
- Centralized path management via aitbc package
- Consistent environment setup across all services
