fix calendar-query.py: use get_display_name(), URL-decode names, fix search API

- Replace deprecated cal.name with cal_name() helper using get_display_name()
- URL-decode calendar names (Formula+1 → Formula 1)
- Use cal.search(event=True) instead of deprecated date_search()
- Default to showing all calendars instead of filtering to Personal
