Update billing navigation and increase test timeout

Changes include updating the user and team billing specs to increase visibility timeout and alter navigation route post-billing. Minor adjustments have been made to the page aesthetics and redirection logic. Also, refactored import statements for code organization purposes. Changes in the build script are also reflected in the commit.
