nesgarboandLinus Rath fa343e0768 fix: hide ICS attachments from email attachment list when invitation banner is shown
When an email contains a calendar invitation, the raw .ics MIME parts
(text/calendar, application/ics, application/icalendar) were showing
up in the attachment list alongside the calendar invitation banner,
which is confusing — the banner already provides the relevant UI.

Filter those MIME types out of the displayed attachment list whenever
the calendar invitation banner is active, reusing the existing
isCalendarMimeType utility from lib/calendar-invitation.ts.
