feat: garden dashboard widgets and manifest completion (task 75)

- getCareDueWidgetRows query: schedule rows due within N days, filtered
  by optional container list, ordered by next_due_at
- getGardenOverviewStats query: plant/container/overdue counts + next care
- CareDueWidget: compact list sorted by urgency, inline log-care button,
  truncates at 10 rows with View all link
- GardenOverviewWidget: stat row (plants, containers, overdue) + next care
  line + garden link
- plant-widget.tsx server component: InlineLogButton uses form action to
  call logCare without client JS or navigation
- manifest: garden.care-due and garden.overview widgets registered;
  resolveConfigOptions returns container list for care-due config picker
- quickAdds: icons updated (leaf/box/droplets), log-care URL ->
  /garden?logCare=1
