Add healthchecks and resource constraints to all services

Added healthchecks:
- adminer: PHP file_get_contents check
- authentik_server: ak healthcheck command
- authentik_redis: redis-cli ping
- paperless_redis: redis-cli ping
- paperless_webserver: curl localhost:8000
- n8n: wget healthz endpoint
- traefik: wget ping endpoint (with --ping enabled)
- tracker-nginx: curl localhost:80

Added resource limits:
- adminer: 512M limit, 128M reservation
- authentik_server: 1G/1 CPU limit, 512M reservation
- authentik_worker: 1G/1 CPU limit, 512M reservation
- authentik_redis: 512M limit, 128M reservation
- paperless_redis: 512M limit, 128M reservation
- paperless_webserver: 2G/2 CPU limit, 1G reservation
- traefik: 512M/0.5 CPU limit, 256M reservation
- tracker-nginx: 256M limit, 64M reservation

All services now have proper health monitoring and resource constraints
to prevent resource exhaustion and improve reliability.
