If a calendar shared with a user has the same name as one of the user's
own calendars (or as another share from a different owner), DAVx5 would
show two calendars with an identical, indistinguishable title. The
shared calendar's CalDAV display name (Calendar.Name, exposed via
displayname/DAVx5's calendar list) now gets the owning user's username
appended in parentheses in that case, e.g. "personal (alice)" — the
underlying calendar path/URL is unaffected, and a user's own calendars
are never renamed (only shared ones can collide with something else).
internal/caldav/backend.go: calendarMeta split into calendarMeta (own
calendars, unchanged name) and calendarMetaNamed (explicit display name);
new sharedDisplayName(requester, owner, realName) checks requester's own
calendars and other shares for a collision. Wired into both
ListCalendars and GetCalendar (the latter used by direct
PROPFIND/REPORT against a shared calendar's own URL).
