feat: implement all 15 fxt CLI commands with real gRPC calls

- 13 commands with full gRPC implementations: service, train, tune,
  model, trade, broker, agent, data, risk, config, cluster, auth, backtest
- Streaming support: train logs --follow, broker executions --follow
- --json output on every command via OutputFormat/HumanReadable
- Fix web-gateway monitoring URL default (50057 → 50051, API Gateway)
- Rewire 7 remaining build.rs to consolidated proto/ root (web-gateway,
  backtesting_service, training_uploader, 3 test crates, e2e)
- Fix web-gateway ml_training.proto new fields (mode, max_epochs, resume)
- 75 fxt tests + 139 web-gateway tests, 0 clippy warnings, workspace clean
