Adds a new CLI subcommand that connects to the monitoring service via
gRPC to display live training metrics. Supports single-snapshot mode
(--once), model filtering (--model), and configurable streaming
interval. Renders per-model epoch/loss table, GPU telemetry, hyperopt
progress, and health counters.

Copy broker_gateway.proto from broker_gateway_service into fxt/proto/
and wire it into build.rs compile_protos + lib.rs proto module so the
CLI can call BrokerGatewayService RPCs (health check, account state,
session status).
