Lukas 90f4c6239c Add resource limits to all Docker containers ...

- fail2ban: 0.5 CPU / 128M memory limit, 0.1 CPU / 64M reserved
- backend: 2.0 CPU / 512M memory limit, 1.0 CPU / 256M reserved
- frontend: 0.5 CPU / 128M memory limit, 0.25 CPU / 64M reserved

Prevents 'noisy neighbor' scenarios where one container exhausts
host resources (CPU, memory, disk). Limits are hard caps; reservations
guarantee minimum allocation to prevent OOM kills and ensure
responsive service even under load.

Fixes resource contention issue in production and staging environments.
