Lucas Berger a9d3de658e fix(03): correct event-write timezone + per-user calendar identity (Gate 2 Part D)
BUG A — timed events written 4h off: EventForm sent a naive local wall-clock
string with no offset; the UTC API container parsed it via new Date() as UTC, so
09:00 America/Toronto serialized to DTSTART:...090000Z. Fix: new
apps/pwa/src/lib/eventDateTime.ts serializes timed events to an unambiguous UTC
instant in the browser (where the operator's zone is known); all-day stays a DATE
string. No backend change.

BUG B — created events attached to the wrong user's calendar + duplicate calendar
rows per poll: calendars had no unique key on url, and poller/sync matched
calendars by url alone — so under the shared single Fastmail account (D-16) one
member's collection resolved to the other member's row. Fix: composite
unique(user_id, url); scope poller lookup + sync select to (userId, url); hand
migration 0001 (dedup + add key), applied to the live DB.

Regression tests fail against the buggy url-only predicate. API 98/98, PWA 140/140,
tsc clean both packages.

/**
* Broker: syncCalendar event upsert + all-day handling
*
* Tests syncCalendar in src/broker/sync.ts.
* Key behaviors verified (D-13, T-03-05):
* - All-day events: dtstart_date (DATE) set, dtstart_utc NULL, allDay=true
* - Timed events: dtstart_utc (TIMESTAMP UTC) set, dtstart_date NULL, allDay=false
* - UID used as idempotency key: second sync of same UID is an upsert, not duplicate
* - Raw VEVENT blob stored verbatim
* - Calendar ctag/syncToken updated after sync
