Added decorator `@get_user_params()` to various route handlers in `routes.py`. Adjusted user handling in `config.py` by eliminating checks for 'login' and directly accessing user parameters from Flask's global variable `g`. Also moved user retrieval process from `routes.py` to lower level operations allowing for better abstraction and less redundancy.
Imported user module to the routes module and added a user parameter decorator to the save_config route. This parameter fetches the user ID, which is then used to fetch the username. This username is passed to the upload_and_restart functions as a login argument.
