Onboarding-Login and Signup Frontend Functionalitites

[MGLarsenSW]

Description

This pull request is the almost-complete frontend functionality of the relevant PBI of the Onboarding team.

Changes

Changed the layout of the "Login", "Signup" pages, and added a "Welcome" page. The Login and Signup pages communicate correctly with the backend, and as a result their functionalities work as intended. The user cannot access certain pages if they do not have an authentication token, and vice versa cannot access Login and Signup if they have an authentication token. Added a "Sign Out" functionality, which clears the token from the storage, once again preventing and allowing access to certain pages. The Login page notifies the content creator if their login credentials are incorrect. New content creators must now enter their password twice, in order to sign up properly. Updated "hide password" icon.

Related Issues

The layouts of Login, Signup, and Welcome are not properly implemented: their layout on different screens may vary. Additionally, some screens may find certain buttons inaccessible without the use of the tab button,

  Notes for Reviewers

  The styling of Login, Pages, and Welcome are not finished, and incredibly messy: some styling elements overlap in certain places, making for a lot of unnecessary code. Will be fixed in next sprint :)

This is clearly not an active PR anymore. Last commit was 9th october. Closing. Reopen if you disagree.
