To include more HTTP error codes as existing applications

It has been found that when we scan and find available ports, some error codes are not handled correctly and conclude to no application as being present, while it is obvious that there is a page and code available.

One example is this when scanning Vitalia.es on preprod environment :

2025-07-15 08:49:12.566976 DEB GetLinks 18 Status of https://www.vitaliahome.es:8443 is Bad Request
2025-07-15 08:49:12.568744 DEB GetLinks 18 Cannot read headers of https://www.vitaliahome.es:8443 

While there is indeed an application as this screenshot proves :

We should be handling more HTTP error codes as indicative of the presence of an application though returning "bad request" when it is obvious that a page actually exists.
