Auth Protection for Profile Routes

[aaronchan32]

Changes

• Fixed bug where textfields without custom onChange logic would have a delay for their value. This can be tested by typing in a textfield and quickly pressing enter after to submit the form. The form's value will be empty if this is done too quickly
• Added auth protection to all profile routes using verifyAuthToken middleware. Also attached userId to request if auth token is valid in backend/src/validators/auth.ts
• Minor UI bug fixes

Testing

• Ran through the same tests in PR 86
