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, 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.

 # Completed Steps
 
+- 2026-10-02: On the Applications list, a long repository URL now wraps within
+  its column instead of making the table wider than its card, which cut off the
+  Actions column and the Deploy buttons. In a window too narrow for the table,
+  the card scrolls sideways instead of cutting the table off (#262).
+
 - 2026-10-02: `.dockerignore` leaves out `.git/config`, so a remote URL there
   that carries a credential no longer goes into the Docker build; the image
   still shows the commit it was built from (#269).
