Users can now toggle which meal types (breakfast, lunch, dinner, snack)
are displayed in the meal planner via a new Settings section. Preference
is stored household-wide in sync_config and applied as a filter on the
meals page. Includes preferences API, i18n (DE/EN/IT), and Settings UI.
Replace all — with - in all source files (JS, CSS, HTML, JSON,
Markdown) for consistency and readability.

Admin can now enter CalDAV URL, Apple-ID and app-specific password
directly in Settings; credentials are tested live before saving and
stored in sync_config (take precedence over .env); disconnect clears
DB-stored credentials without server restart. Auto-sync interval
(15 min, configurable via SYNC_INTERVAL_MINUTES) was already in place.
