[#211] Connect setting page

[KirstyGong]

Description:

Added and tested the login function. Changed the routing to make it more clean.

Cypress test fails cause of shitty implementation of auth state through localstorage. Since localstorage is fetch no components know when the login state is changed.

• remove localstorage token/username to context
• add method to login in cypress
• fix up cypress folder structure
