Notification upgrades: lifecycle, configurable levels, summaries

- NOTIFY_LEVELS chooses which event levels are sent (default trade,error).
- NOTIFY_LIFECYCLE sends explicit start/stop messages; the kill switch always
  notifies at error level.
- SUMMARY_INTERVAL_MINUTES sends a periodic portfolio summary (equity, per
  strategy P&L, allocation, halted state) via a background task started with
  the run and stopped on stop/kill/shutdown.
- Wires the new vars plus the go-live vars through both compose files and the
  deploy workflow. Adds tests.
