Dev compose improvements master

1. Set the max connections to 20, I frequently see db-1 | 2026-08-23 08:57:02.784 UTC [12641] FATAL: sorry, too many clients already 2. Add a wildcard route in Traefik to serve DID documents locally. 3. Expose the PLC port locally so I can point an app at `http://localhost:2582` and be able to do full OAuth flows.
