Gonçalo Rodrigues 8436295bbc feat(infra): gate observability stack behind var.enable_monitoring (#38)
Adds enable_monitoring variable (default true) that controls whether
Prometheus/Grafana, Loki, Fluent Bit, and Jaeger are deployed.
Setting it to false saves ~1.5 GB RAM, making the stack viable on
a 2–4 GB VPS without touching the application services.

Also caps MongoDB WiredTiger cache at 256 MB (--wiredTigerCacheSizeGB=0.25)
so it doesn't balloon on memory-constrained hosts.
