- read risk_level with risk fallback (was: risk only → "unknown" for
all actions written by supervisor which uses risk_level key)
- include description field in alert format (was: alert_only payloads'
substance was invisible — description carried the full message)
- extract _format_pending_action() pure helper to enable unit testing
without a live Telegram connection
- 8 tests: risk_level present, risk fallback, both absent, description
shown/absent, truncation, full HA alert_only shape, no-description no-crash
- flagged during Phase 5 review of ha-diag-agent supervisor routing
