fix: update CLI default RPC port from 8006 to 8005

Fixed CLI blockchain connection timeout errors by updating default RPC URL
from port 8006 to port 8005 across all CLI modules.

Root cause:
- Port 8006 is for blockchain P2P protocol (not HTTP RPC)
- Port 8005 is the HTTP RPC API port
- CLI was trying to use HTTP on port 8006, causing timeouts

Updated files:
- cli/advanced_wallet.py: DEFAULT_RPC_URL
- cli/enterprise_cli.py: DEFAULT_RPC_URL
- cli/commands/blockchain.py: _get_node_endpoint()
- cli/core/main.py: default_rpc_url
- cli/commands/sync.py: source and import-url defaults
- cli/commands/marketplace.py: rpc_url config default
- cli/commands/blockchain_event_bridge.py: test mode config
- cli/handlers/bridge.py: test mode config
- cli/commands/deployment.py: service endpoints

This fixes the training script errors where CLI commands were timing out
when trying to connect to the blockchain node.
