Adds a one-way push (ApiCore -> M365) of Aufgaben/Durchsichten/
Behandlungen/Fütterungen/Ernten/Königinnen-Zuordnungen into the calendar
of a Microsoft 365 group, via the Graph API.
- CalendarSyncModule (app-only client-credentials Graph auth, separate
from the interactive SSO app registration; new env vars
M365_CALENDAR_TENANT_ID/_CLIENT_ID/_CLIENT_SECRET).
- Outbox + minute-interval cron worker (CalendarSyncOutboxEntry) instead
of a synchronous push, since Graph calls are too slow/flaky to block a
domain create request on; failed syncs retry up to 5 times.
- Per-source-type toggle plus a group-ID field, configurable in
Verwaltung > Automatisierung > Kalender-Sync (Verwaltung > Backup, an
env var still wins on those fields where one applies to related config).
- Hooked into Tasks/Inspections/Treatments/Feedings/Harvests/Queens at
their existing create (and Task update/complete) points; entries render
as all-day Graph events to avoid timezone ambiguity.
- Documents the design decision in ARCHITECTURE.md (Annahme 9), since
this is a net-new capability the lastenheft doesn't scope.
