Improve locale matching in FrontendPageController

The code was updated to more effectively match the request locale with the allowed locales in the FrontendPageController. In cases where there's no match, the first allowed locale is employed. This change enhances the readability and clarity in handling locale-related variables. Additionally, unused 'ContentSecurityPolicyHelper' was removed and default status updated to 'status_published'.
