chore: Enhance CI workflow summary and improve JWT token generation

This commit updates the CI workflow summary to provide a clearer overview of job results and their purposes. It also modifies the JWT token generation in the authentication API to include a unique identifier (`jti`) for both access and refresh tokens, improving token management. Additionally, the test for the token refresh endpoint is adjusted to ensure it verifies the new access token correctly.
