fix: default import target to the first local calendar

The pre-selected target was calendars.first() (raw provider order), which
could land on a synced calendar mid-list while the picker shows local
calendars first. Default to the first local calendar so the checkmark lines
up with the top row; fall back to the first calendar when none are local.
