services/events.py::list_events treated any event with end_dt IS NULL
as perpetually matching, so a point-event created last week would be
returned as "happening today" whenever the briefing or list_events
tool queried today's window. That manifested as briefings claiming
past events were scheduled for the current day.
Split the null-end branch: point events now only match when start_dt
falls within [date_from, date_to]. Events with an end_dt continue to
use standard overlap logic.
This bug affected both the legacy briefing synthesis and the agentic
list_events tool path, since both call the same events service.

- RRULE expansion: list_events now expands recurring events into
individual occurrences within the query window using python-dateutil
- CalDAV pull sync: new caldav_sync.py + POST /api/events/sync route;
imports remote events into the internal store by caldav_uid
- Past event search: search_events accepts include_past=true to search
historical events; exposed in the LLM tool definition
- Internal reminders: migration 0037 adds reminder_minutes +
reminder_sent_at columns; event_scheduler.py checks every 5 min and
fires push notifications; CalDAV sync job runs hourly
- reminder_minutes now stored and returned in create/update routes + tools

Backend:
- tools.py: apply UTC normalization to update_event datetime fields
(matched create_event which already did this)
- events.py service: allow end_dt/recurrence/project_id to be cleared
via update_event by permitting None for nullable fields
- events.py service: find_events_by_query now returns upcoming events
first, falling back to past — prevents AI tools from mutating stale
past events when a future match exists
- events.py service: list_events now uses overlap logic (start <= to
AND end >= from) so multi-day events spanning the query boundary
are included; previously only start_dt was checked
Frontend:
- ToolCallCard: fire fable:calendar-changed on created/updated/deleted
so CalendarView refetches without requiring a manual page refresh
- KnowledgeView: replace raw apiGet('/api/events') with listEvents()
client function; also fix today bar which was reading .events off a
flat array (always empty) — now correctly receives EventEntry[]
- HomeView: use full ISO strings for event date range instead of naive
UTC-midnight strings; deduplicate inline date math via _dateRange()
