Docker Compose interprets $ as variable substitution, so we need to escape
Dokploy's project-level variable syntax by doubling the dollar sign.
Changes:
- docker-compose.*.yml: ${{project.VAR}} → $${{project.VAR}}
- Updated DOKPLOY_DEPLOYMENT.md with correct syntax and explanation
- Updated SHARED_PROJECT_DEPLOYMENT.md with correct syntax and explanation
This fixes the 'You may need to escape any $ with another $' error when
deploying via Dokploy.
Evidence: Tested in Dokploy deployment - error resolved with $$ escaping.
