fix(dashboard): filter todayMeals by visible_meal_types preference (#14)

The dashboard meal widget was showing all meal types regardless of the
household meal visibility settings configured in Settings > Meal Plan.

Root cause: the todayMeals SQL query in dashboard.js did not read
visible_meal_types from sync_config. The Meals page applied this filter
client-side, but the dashboard API returned unfiltered data.

Fix: read visible_meal_types from sync_config before the query and inject
the active types as IN (?) placeholders. Falls back to all four types when
no preference is stored.
