Subject: [PATCH] fix: export isCalendarMimeType for use in email attachment
 filtering

Previously isCalendarMimeType was a module-private function in
lib/calendar-invitation.ts. Exporting it allows the email viewer
to reuse the same MIME type detection logic when filtering out
calendar attachments, avoiding duplication of the type set.
