Root causes:
1. parseRRule did not strip the "RRULE:" prefix stored by the ICS parser,
causing all recurrence rules from CalDAV sync to silently fail parsing
2. YEARLY frequency (used by birthday events) was not supported
3. expandRecurringEvents filtered instances only by start date, missing
multi-day events that start before the view window but span into it
4. All-day recurring instances got datetime end values instead of date-only
Fixes#5 (follow-up from @tschig)

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.

expandRecurringEvents() iterates from the event's original start date,
generating all occurrences within the requested window using the existing
nextOccurrence() service (max 1000 iterations). The SQL query is extended
to also fetch recurring events that started before the window. Event
duration is preserved across instances. Virtual instances carry
is_recurring_instance=1 and are shown with a repeat icon in the agenda
view. /upcoming expands across a 90-day forward window.
Closes BL-01.
