Description

Adds a view for editing the title and description of an AuthorList. This view can be used for simply editing those properties of an existing list or as the first step in a list-creation wizard (step 2 coming in a separate PR).

Note: There were also some intentional, very minor changes to the layout of the NosForm/NosSection components to match the lists design. This will make the same change everywhere they are used, such as on the edit profile view (see before/after below).

How to test

Creating (only step 1 for this PR):

1. Open the side menu
2. Tap "Your Lists"
3. Tap "New" button at top right
4. Enter a name and description for the list.
   Note: The "Next" button does nothing for now.

Updating:

1. Open the side menu
2. Tap "Your Lists"
3. Tap the ellipsis button on one of your lists
4. Edit the name and description
5. Tap the "Save" button at top right
   Your changes are saved and the view is dismissed.
