Activity: each feed/sleep/diaper row independently tappable in 4-day strip

Each row in a day chip is now its own button. Tapping 🍼×2 on Thursday
opens a sheet scoped to feeds on Thursday only — not all logs for that day.
Sheet shows entries for that specific type, with edit/delete per entry and
a single focused "+ Add [type]" CTA at the bottom.
Rows showing ×0 render dimmed so missing entries stand out at a glance.
