Update Traefik version and configuration

Switched the Traefik container image to version v3.2 to utilize updates in the latest release. Enabled the insecure dashboard mode for testing purposes. Added a port mapping for the Web UI to allow access. Updated environment variables to consistent names, ensuring more readable and maintainable configuration. Recognize these changes may pose security risks if used in production without adjustments.
