fix(docker): Add build context to app-dev service in docker-compose.yaml

Fix invalid docker-compose configuration by adding missing build context properties to app-dev service.

This PR resolves the following error:
"ERROR: The Compose file is invalid because: Service app-dev has neither an image nor a build context specified. At least one must be provided."

Changes:
- Added build.context and build.dockerfile properties to app-dev service
- Aligned build configuration with existing app-prod service structure
