chore(docker): enable files_mcp service in container image

Browse Source 
- Dockerfile: COPY files_mcp package, mkdir -p /app/data/files at build
  time, set ENV FILES_MCP_ROOT=/app/data/files as the default sandbox
  root (overridable at runtime).
- docker-compose.yml: surface FILES_MCP_ROOT in the env block with the
  same default, so operators can override it via .env or -e.

FILES_MCP_ROOT must exist at process start (path_guard._init_root
checks is_dir()), so the directory is created during build rather than
deferred to entrypoint — fail-fast at image build beats a runtime
RuntimeError on every container start.

Default lives under /app/data so it rides the existing data volume
(./data:/app/data) and persists across container restarts alongside
connections.json / pending_jobs.json / logs/.

Verified locally: docker compose config --quiet passes; FILES_MCP_ROOT
resolves to /app/data/files in the rendered config. Full image build
not run (docker daemon unavailable in this environment); please run
`docker compose up -d --build` to confirm in your environment.
