refactor(ui): make an event row a single open target

The row already opened the event; the tick sat on top of it, so the two
smallest targets on the page did different things a few pixels apart.
"Done" was never the only thing a reader wants to say about an event
either — status, effort and notes all live in the detail sheet.

The tick becomes a chevron: decorative, aria-hidden, and leaning towards
where the row is about to take you on hover. The full-bleed button is
the only control, so there is no second stop for anyone tabbing or using
a screen reader. Undo on a revealed ignored row stays a real button —
it is a real action with nowhere better to sit.
