Add weather badge, chore chart, fix controls grid

- Header now shows weather icon + temp from weather.forecast_home_2 next
  to the connection badge (right side of nav bar)
- New ChoreChart widget below TodoWidget on Home view; reads from
  todo.chores HA entity; items prefixed with a name (Becca: / Chris: /
  Arabella:) get per-person color coding matching the calendar palette;
  tap toggles completion
- Controls overlay simplified from grid-cols-12 auto-rows-min to a plain
  grid-cols-2 — removes the uneven gaps between widgets
