Show the deploy branch in the app page title and early in the app list (closes #240)

The app page shows the configured branch as a neutral label next to the
status badge; the line under the title now shows only the repository.
The app list moves the Branch column to right after Name and lets the
table scroll sideways inside its card, so narrow screens no longer cut
columns off. A new test renders both pages for an app on a non-main
branch.
