Simplification of authentication middleware

[fsantin1985]

Problem

The code currently has a dual approach to session management (Redis for passkeys, JWT for passwords)

Solution

• Creation of an abstract SessionManager class (unified interface) with concrete implementations for each strategy

Additional information

This would simplify authentication middleware and make the code more maintainable
