Calendar: CalDAV two-way sync (iCloud/generic) + all-day timegrid fix
CalDAV account connect (Settings → Calendars) with RFC 6764 discovery, per-calendar vaulted credentials, and full two-way sync verified live against NextCloud: - caldav.py: discovery, calendar-query REPORT (pull), PUT/DELETE with quoted ETags (If-Match/If-None-Match), iCloud partition-redirect handling, ICS build/parse; clear error codes (auth/private-host/ unreachable) surfaced to the connect UI. - sync.py: ctag-gated pull + push of local changes; dirty rows protected from being clobbered; 15-min cron + immediate enqueue on every create/edit/delete so changes reach the server in ~1s. - Dirty tracking via a BEFORE INSERT/UPDATE trigger (migration 0007), suppressed during sync with a txn-local GUC; deletes tombstone then DELETE server-side. Writability now driven by server privileges. - migration 0006: event uniqueness NULLS NOT DISTINCT — fixes duplicate events on every full re-pull (NULL recurrence_id never matched ON CONFLICT). - 5 CalDAV parsing unit tests. Calendar UI (page.js): all-day events now render in Day/3-days/Week views (were month-only). They share the timed-event column layout so overlapping events sit side-by-side, fill the day column vertically with a sticky label, and are matched by start day (fixes UTC-midnight events spilling into the next local day).

The event key is ``(calendar_id, ical_uid, recurrence_id)``. ``recurrence_id`` is

NULL for the common case (non-recurring events and recurring masters). Postgres

treats NULLs as *distinct* in a unique index by default, so the CalDAV pull's

Two-way sync needs to know which events changed locally so the pusher can PUT/DELETE

them back to the server. Rather than thread dirty-marking through every mutation
|

endpoint (create / patch / edit-following / delete with its recurrence scopes), a
|

BEFORE INSERT OR UPDATE trigger sets ``dav_dirty`` on any row belonging to a
|

``caldav`` calendar.

The pull sync itself writes these rows too, so it must NOT re-mark them dirty (that

would push server state straight back). It signals "this write is a sync" by setting
|
||||
the transaction-local GUC ``webmail.dav_sync = 'on'``; the trigger skips when it sees
|

that. Deletions are tombstoned by the endpoint (``dav_deleted``), which is an UPDATE

and so also flows through this trigger.
