✅ PHPCS: Fixed all errors reported on GitlabCI:

• Fixed all validation errors such dependency injection, code formatting, use states ordering and any other issues reported.
• Required phpcs and phpstan validation jobs to pass.

Mostly:

• Automated fixes with: phpcbf web/modules/contrib/colorbox/
• Fixed the remaining issues manually.

Testing locally: phpcs web/modules/contrib/colorbox/, with the correct phpcs.xml.dist file.
