This pull request refactors the SecurePathController to improve the handling of signed URL validation by separating signature expiration and validity checks, and simplifies the getUrl method by removing unnecessary parameters and logic. Additionally, the hasCorrectSignature method has been removed in favor of using Laravel's built-in hasValidSignature method.

Note that this new functionality relies ENTIRELY on a proper Nginx configuration.

Improvements to signed URL validation:

• Refactored the signature validation logic in SecurePathController to first check for signature expiration using signatureHasNotExpired and then validate the signature using Laravel's hasValidSignature method. This improves clarity and leverages framework capabilities. (app/Http/Controllers/SecurePathController.php, app/Http/Controllers/SecurePathController.phpL36-L54)

Simplification of URL generation:

• Simplified the getUrl method by removing the $absolute parameter and redundant logic for handling query strings. The method now directly uses $request->url() combined with filtered query strings. (app/Http/Controllers/SecurePathController.php, app/Http/Controllers/SecurePathController.phpL75-R78)

Code cleanup:

• Removed the custom hasCorrectSignature method, as its functionality is now replaced by Laravel's hasValidSignature method, reducing duplication and improving maintainability. (app/Http/Controllers/SecurePathController.php, app/Http/Controllers/SecurePathController.phpL75-R78)
