feat(03-12): GREEN — WR-03 blank edit, WR-03 recurrence, WR-05 zone-consistent, IN-03

WR-03 blank: add occurrence?.uid to reset effect deps so form re-populates
when occurrence resolves in TanStack cache after form opens.

WR-03 recurrence: derive initial recurrence from occurrence?.recurrence
instead of hard-coding 'none'; defaults to 'none' when absent (v1 comment).

WR-05: rewrite parseDateTime to use getFullYear/getMonth/getDate/getHours/
getMinutes (all local accessors) — never mix toISOString() UTC date with
getHours() local time.

IN-03: export todayIso from calendarStore (was private); import into EventForm
and collapse getDefaultStartDate/getDefaultEndDate to todayIso() calls.
