Introduces dynamic issuer validation in the OnTokenValidated event, comparing the token value with the current request host (scheme + host). In case of a mismatch, authentication fails and a standardized error (InvalidIssuer) is logged in HttpContext.Items. It also adds handling for invalid token formats with a specific error (InvalidTokenFormat), ensuring more consistent and traceable responses in the authentication flow.
