Stabilize Docker startup and runtime proxy

Browse Source 
Reduce cold-start stalls by raising the default backend memory limit, bounding heavy feed concurrency, preserving non-empty startup caches, and refreshing working news feeds. Fix the Next API proxy for Docker control-plane writes by stripping unsupported hop/body headers and forwarding small request bodies safely. Keep the dashboard dynamic so production users do not get stuck on a cached startup shell.

> **Backend port already in use?** The browser only needs port `3000`, but the backend API is also published on host port `8000` for local diagnostics. If another app already uses `8000`, create or edit `.env` next to `docker-compose.yml` and set `BACKEND_PORT=8001`, then run `docker compose up -d`.
> **Blank news/UAP/bases/wastewater after several minutes?** Check for backend OOM restarts with `docker events --since 30m --filter container=shadowbroker-backend --filter event=oom`. The default compose file gives the backend 4GB; if your host has less memory, reduce enabled feeds or set `BACKEND_MEMORY_LIMIT=3G` and expect slower/heavier layers to warm more gradually.
> **Podman users:** Podman works, but `podman compose` is a wrapper and still needs a Compose provider installed. On Windows/WSL, if you see `looking up compose provider failed`, install `podman-compose` and run `podman-compose pull` followed by `podman-compose up -d` from inside the cloned `Shadowbroker` folder. On Linux/macOS/WSL shells you can also use `./compose.sh --engine podman pull` and `./compose.sh --engine podman up -d`.
