Improve devcontainer configuration

- Simplify Dockerfile: use golang:1.24 base, install Node via features
- Add proper port forwarding for Pulse (7655 frontend, 7656 API)
- Add Vue Volar extension for frontend development
- Add start-pulse-dev.sh helper script for auto-starting dev server
- Add FRONTEND_DEV_HOST to containerEnv for proper binding
- Add .env.devcontainer to .gitignore (local override file)
- Update frontend dependencies
