feat(jwt): add azp claim to ID token (#3570)

Added the `azp` (Authorized Party) claim to various JWT token structures
including Claims, ClaimsShort, ClaimsWithoutThirdIdp, and ClaimsStandard.
Updated the generateJwtToken and getClaimsCustom functions to handle the
new claim. This change aligns with the OpenID Connect specification.
