fix(tasks): open the task by clicking its text, links carved out

The first cut put an open-button overlay over the row, which intercepted
every click on the title text — nine smoke tests (and real users) open a
task by clicking its text, and the overlay stole those clicks. Make the
body a role=button instead, with each link stopping its own click from
bubbling: plain text opens the task, a link opens the page.
