UTC midnight passed to FullCalendar's timeZone:'local' was being
converted to local time, shifting all-day events back by 1+ days for
users in UTC-X zones. The edit form had the same bug via new Date().
Fix: pass YYYY-MM-DD slices (UTC date) for all-day events in both
toFcEvent and EventSlideOver resetForm, bypassing timezone conversion.

- Frontend sends user_timezone (IANA, from Intl.DateTimeFormat) with
every message POST; threaded through route → generation_task → build_context
- System prompt now tells the LLM the user's timezone so it creates
events with the correct UTC offset (e.g. 15:00+01:00 not 15:00Z)
- Calendar tool guidance updated to require UTC offset in all event
datetimes
- EventSlideOver: dateFromIso/timeFromIso now use JS Date to convert
stored UTC times to local time for display; toIso includes local
timezone offset when saving so the correct UTC time is stored

- AI calendar tools now always available (moved from _CALDAV_TOOLS to _CORE_TOOLS);
create/list/search/update/delete events go through the internal DB store first,
with fire-and-forget CalDAV push sync when the user has CalDAV configured
- Add EventEntry interface and typed API helpers (listEvents, createEvent,
getEvent, updateEvent, deleteEvent) to client.ts
- Install @fullcalendar/vue3, daygrid, timegrid, interaction, core packages
- Add EventSlideOver.vue: create/edit/delete slide-over with title, start/end,
all-day toggle, location, description, color picker, and project selector
- Add CalendarView.vue: month/week/day FullCalendar with drag-drop and resize
wired to PATCH /api/events/:id; click empty date opens create slide-over
- Wire /calendar route, Calendar nav link in AppHeader, g+l keyboard shortcut
