Remove "viewerDateFrom" / "viewerDateTo" in favor of CalendarDateTime methods

Summary: Ref T10747. The CalendarDateTime object now carries the viewer timezone as part of its state, so we don't need to have separate accessors.

Test Plan:
  - Viewed events, checked that crumbs render properly.
  - Edited events.
  - Created new events.
  - Viewed calendar.
  - Viewed event detail pages.
  - Viewed profile mini-calendar.
