feat(backend): Add last_sign_in_at filters to getUserList

[Jibaru]

Description

Add support for filtering users by last sign-in timestamp ranges in the getUserList API method. This enables developers to query users based on when they last signed into their application.

The new parameters use exclusive comparison operators:

• lastSignInAtAfter: Returns users where last_sign_in_at > value
• lastSignInAtBefore: Returns users where last_sign_in_at < value

Both parameters accept Unix timestamps in milliseconds and can be used independently or combined to create date ranges. The filters are applied to both the /users and /users/count endpoints to ensure consistent pagination.
