fix: move EXDATE with the series when its times change (#248)

Dropping a single occurrence on a calendar with no _sync_id records it in
the master row's EXDATE (the #47 fix; synced calendars use a cancelled
exception instead and are unaffected). An EXDATE stamp is an absolute
instant — it excludes an occurrence only while the series keeps generating
one at exactly that instant — and nothing ever rewrote it when the anchor
moved.

buildEventUpdateValues shifts DTSTART on any time change and rewrites
RRULE/DURATION/zone/all-day, so every occurrence regenerates elsewhere
while the stamps stay behind matching nothing: the occurrence the user
deleted comes back. updateEventFromOccurrence is worse — it splits the
series by inserting a fresh event built from the form, which carries no
EXDATE at all, so every exclusion in the tail is lost.

Shift each stamp by the same wall-clock delta the anchor takes, re-resolved
in the event's (possibly new) zone. Reusing the anchor's rule is what keeps
an exclusion pinned to its occurrence when a DST boundary sits between the
two, or the zone itself changed; a millisecond delta would bake in the
offset that happened to apply at the edited occurrence. Parsing reads
all-day-ness from the old form and writing takes it from the new one, so
the VALUE=DATE and date-time forms convert into each other when the event
switches — the wrong form matches no occurrence and loses the exclusion
just as surely as the wrong instant.

Stamps in a shape Calendula never writes (a TZID-parameterised or floating
one from a sync adapter) are left exactly as they are, whole list included:
a stale stamp excludes nothing, but a mangled one could exclude the wrong
occurrence.

For the split, the parent's stamps past the cutoff are re-timed onto the
new series. The one *at* the split point is dropped: it names the
occurrence being edited, which exists by definition, and honouring a stale
exclusion for it would swallow the edit whole. The parent keeps its full
list — stamps past the truncation are inert once it stops generating those
occurrences. The write repeats the whole time/recurrence set for the reason
#47 documents (an EXDATE-only update is not read as a recurrence change),
and a failure rolls the new series back before the parent is truncated, so
the split fails whole rather than landing with the exclusions dropped.

Dropping the recurrence now clears EXDATE with the RRULE. Dormant rather
than harmless: adding a recurrence back later would punch the old holes
into the new one.

This reaches every calendar type through the "all events" path, including
synced ones, where an upstream EXDATE must move with the series for the
same reason — and reaches a calendar move too, which copies EXDATE verbatim
and then applies the field edits as a normal series update.

+- **A deleted occurrence no longer comes back when the series is re-timed.**
+  Delete a single occurrence of a repeating event, then change the time of the
+  whole series, and the occurrence you had removed reappeared. Doing it the
+  other way round — "This and all following events" — lost every removal in the
+  part of the series being changed. Removals now travel with the event: they

+  day, a timezone change and a switch to or from an all-day event, and they
+  carry over when a series is split. Repeating events on your device's own
+  calendars are affected, including the birthday and anniversary calendars
