chore: cap container memory in docker compose

Browse Source 
The API container used server garbage collection. Server GC makes one heap per
CPU, which is 22 heaps on this host. The two frontend containers sized the Node
heap from host RAM (16 GB), because compose sets no cgroup limit.

Set DOTNET_gcServer=0 and NODE_OPTIONS=--max-old-space-size=2048. This bounds
the memory that `docker compose up` needs.
