Keep the Applications list's table inside its card (closes #262)

Table cells never wrap, so a long repository URL made the table wider
than its card, which hides what does not fit and so cut off the Actions
column and the Deploy buttons. The repository URL now wraps within its
column, with a minimum width of 8rem so it stays readable in a narrow
window, and the card scrolls sideways when the table still does not
fit. A handler test checks both. Every class used was already in the
committed static/css/tailwind.css.
