Phase 7 follow-up: 1-month body retention and actions_log cap (AUD-75)

Browse Source 
Implements the AGENTS.md §7 data rule: keep message bodies for one month, and
size-cap the append-only action log.

- internal/store/retention.go: Store.Retain clears messages.body_text older
  than the window (metadata stays) and deletes actions_log rows beyond the
  newest N, in one transaction.
- internal/config: EMAIL_AGENT_RETENTION_DAYS (30) and
  EMAIL_AGENT_ACTIONS_LOG_MAX_ROWS (50000).
- cmd/email-agent: bounded -retain flag for the n8n schedule.
- Tests for body clearing, metadata retention, log cap, and disabled policy.
