[G2M] auth - adds support for account expiry

[amy83762100]

Adds support for account expiration through a new access_expired_at field. If set, the system calculates the JWT token’s expiry based on this value. Once the expiration time has passed, the user is automatically deactivated and blocked.

Changes

• Introduced access_expired_at column (TIMESTAMPTZ) in the user schema
• Updated getUserInfo to deactivate user if access has expired
• JWT TTL is now dynamically computed based on access_expired_at
• If the access has expired, the user is deactivated and an AuthorizationError is thrown with a clear user-facing message.
