fix(training): bundle reference content + use docker bridge gateway

The Style Studio's curator-prompt + chat features read reference docs
from disk at runtime. Two issues from the initial production run:

1. Dockerfile + .dockerignore excluded .claude/, docs/, and most of
   skills/. Now COPY the four specific files the new endpoints need:
     - .claude/agents/hermes-curator.md
     - skills/decision/SKILL.md
     - docs/legal-decision-lessons.md
     - docs/corpus-analysis.md
   .dockerignore opens whitelists for just those files.

2. Coolify's custom_docker_run_options=--add-host=host.docker.internal:host-gateway
   is not honored on dockerimage build_pack apps (ExtraHosts stayed []).
   Switch chat_proxy.py default to http://10.0.1.1:8770 — the docker0
   bridge gateway, same pattern Paperclip uses for 3100. Bind the host
   pm2 service to 0.0.0.0:8770 so the container can reach it via the
   bridge IP. Oracle Cloud's security list keeps the port unreachable
   from the public internet.
