Hot reload controlplane local setup

[AbirAbbas]

Summary

Adds Docker-based local development environment with hot-reload for the control plane. When you modify Go files, the server automatically rebuilds and restarts.

What's included

File	Purpose
control-plane/dev.sh	Simple script to start/stop dev environment
control-plane/docker-compose.dev.yml	Docker Compose with SQLite (default) and PostgreSQL modes
control-plane/Dockerfile.dev	Dev container with Go toolchain and Air
control-plane/.air.toml	Air configuration for hot-reload
control-plane/README.md	Documentation for local Docker development
.gitignore	Added tmp/ for Air build artifacts

Usage

cd control-plane
./dev.sh            # SQLite mode (default, no dependencies)
./dev.sh postgres   # PostgreSQL mode
./dev.sh down       # Stop containers
./dev.sh clean      # Stop and remove volumes

The server runs at http://localhost:8080 and automatically reloads when .go, .yaml, or .yml files change.

Technical details

• Uses Air v1.61.7 for hot-reload (compatible with Go 1.24)
• Go build cache and module cache persisted in Docker volumes for faster rebuilds
• Web UI not included in dev mode (run npm run dev separately if needed)

Testing

• Verified Docker build succeeds
• Verified hot-reload triggers on file changes
• ./scripts/test-all.sh

Checklist

• I updated documentation where applicable.
• I added or updated tests (or none were needed).
• I updated CHANGELOG.md (or this change does not warrant a changelog entry).
