Ensure liveness, readiness and startup probes on all workloads

Every container in every Deployment/StatefulSet now defines all three
probes. The paperless-ngx consume CronJob intentionally has none (batch
workload).

- Add probes: apache-tika, calibre-web-automated, cyberchef, gotenberg,
  homeassistant, patchmon-backend, samba (tcp/445), teamspeak-server
  (tcp/30033), zipline (/api/healthcheck)
- Fix voucher-vault null probe values with real defaults
- Fix startup-probe semantics in template-chart and rallly (no
  initialDelaySeconds, generous failureThreshold)
- Switch outline probes to its /_health endpoint
- Add readiness/startup probes to satisfactory
- Add startup probes to matrix-synapse, matrix-delegation-nginx,
  paperless-server, patchmon-frontend, urlaubsverwaltung
- Major version bump for all published charts
