Improve the project manager UI

This incorporates many suggestions from #31342.

This also revises the search behavior to be simpler and more efficient:

- Searching will now search in both the project name and path. A project
  will be displayed if either of these match the search term.
- If the search term contains a "/", the whole path will be used to match
  the search term. Otherwise, only the last path component will be used.
