Bugfix/issue 153 token revalidation

[dsmabulage]

Purpose

The purpose of this PR is to fix #153

Goals

Implement a token refresh flow to ensure continuous authentication by issuing new access tokens when the current ones expire.

Approach

• Added logic to verify the access token and issue a new token using the refresh token when the access token is expired.
• Implemented a method to set both the new access token and refresh token as cookies in the response.
• Updated the authentication middleware to handle token expiration and automatically refresh tokens if a valid refresh token is provided.
