feat(contacts): make email cell a link to the contact detail page

Currently the only entry point from the /contacts list to a contact's
detail page is the small Edit icon-button in the actions column. Make
the email itself a Link to /contacts/:id so the obvious affordance
("click the thing that identifies the row") works too. Applied to both
the desktop table cell and the mobile card variant.
