Changes

• In bootstrap/helpers/shared.php, added checks for array type in parseDockerComposeFile before processing labels. This prevents str() from receiving an array. Array label values are now converted to strings.
• In bootstrap/helpers/docker.php, added checks for array type in fqdnLabelsForTraefik before calling preg_match. This prevents preg_match() from receiving an array. Array label values are now converted to strings.
• Added a unit test file tests/Unit/DockerComposeLabelParsingTest.php to verify these label parsing and conversion behaviors.

Issues
