Improve the visibility/presentation of the Add buttons in the database.
Review Request #12828 — Created Feb. 7, 2023 and submitted
The "Add Repository", "Add User", etc. buttons in the admin UI's change
list pages weren't very visible. They were just ordinary links in the
This change converts them to a primary button presentation. This makes
them stand out clearly, helping users to notice them and know they can
be clicked to create a new entry for something.
The titles have also changed from "Add <object>" to "Add New <Object>",
with the "<Object>" being converted to title case (helping remove some
inconsistencies between different objects).
Went through the admin UI, looking at various model change list pages
and making sure they all looked as expected.
