Add Global Exception Handlers with Clearly formatted Error report when API Resource is not Found

[sprintell]

Wrong general Error Message is given at the moment "Internal server Error" - e.g - for wrong accession-Id
{
"status": 404,
"error": "Internal Server Error",
"message": "GCST904833779",
"timestamp": "2025-02-18T23:16:22.349Z"
}

A more accurate exception message should Logged and return to API user as below

{
"errorCode": 404,
"error": "Not Found",
"errorMessage": "Studies with Accession Id: GCST904833779 not found",
"servicePath": "http://{server}/gwas/rest/api/v2/studies/GCST904833594",
"timestamp": "2025-02-18T23:07:19"
}

This should be for all endpoints - studies, unpublished-studies, single-nucleotide-polymorphisms, publications, efo-traits, body-of-works, and associations
