Improve Docker reliability and document compose usage

[stevo1403]

Summary

• make dashboard opt-in via compose profile (ui) so default startup focuses on API/MCP
• remove obsolete version key from docker-compose.yml
• switch packages/openmemory-js/Dockerfile to node:20-bookworm-slim + npm ci build flow
• increase Node heap during TS build to avoid Docker OOM (NODE_OPTIONS=--max-old-space-size=4096)
• document Docker usage in README (default API/MCP command, optional dashboard profile, health checks)

Validation

• docker compose up --build -d
• verified container starts on :8080 and server boots successfully

Follow-up (clean formatting): addressed Copilot feedback in commit 4220bd1.

• Dockerfile: scoped build memory option to the build command only: RUN NODE_OPTIONS="--max-old-space-size=4096" npm run build
• docker-compose.yml: replaced openmemory wget healthcheck with a Node-based healthcheck so it does not depend on wget in the runtime image

Validation rerun: docker compose up --build -d; service starts and healthcheck runs.
