Mayank Ukey 3799dc102f fix: ICS export — escape X-WR-CALNAME and honour is_utc on DTSTART/DTEND (#1174) ...

Two bugs in the export_ics path:

1. X-WR-CALNAME was written raw: calendar names containing commas,
   semicolons or backslashes produced invalid ICS (RFC 5545 §3.3.11
   requires those characters to be escaped as \, \; and \\).
   Fix: wrap cal.name in the existing _ics_escape() helper, which is
   already used for SUMMARY, DESCRIPTION, and LOCATION on the lines
   immediately below.

2. DTSTART and DTEND on non-all-day events always emitted the naive
   ISO string (e.g. 20260602T100000) regardless of CalendarEvent.is_utc.
   Consumers treat a naive datetime as floating/local time, so UTC
   events imported into Google Calendar or Apple Calendar shifted by
   the user's timezone offset.  Fix: append 'Z' when is_utc is True,
   matching the pattern already used by the serialise_event() helper
   at line 408.
