Viktor Barzin 81bfccaefc fix OOM kills: tune MySQL memory, reduce Nextcloud workers, increase Uptime Kuma limit 
MySQL (3 OOM kills):
- Cap group_replication_message_cache_size to 128MB (default 1GB caused OOM)
- Reduce innodb_log_buffer_size from 64MB to 16MB
- Lower max_connections from 151 to 80 (peak usage ~40)
- Increase memory limit from 3Gi to 4Gi for headroom

Nextcloud (30+ apache2 OOM kills per incident):
- Reduce MaxRequestWorkers from 50 to 10 to prevent fork bomb
  when SQLite locks cause request pileup
- Lower StartServers/MinSpare/MaxSpare proportionally

Uptime Kuma (Node.js memory leak):
- Increase memory limit from 256Mi to 512Mi
- Increase CPU limit from 200m to 500m
