fix: update live test reference data and add Trump tests

- Fix direct-call datetimes to use UTC (server strips offsets):
  Einstein: 11:30 LMT -> 10:37 UTC, Chaka: 21:05 CST -> 03:05 UTC
- Fix true_node to match live server output:
  Einstein: 1.48 -> 2.73, Chaka: 9.73 -> 11.14 (non-retro)
- Add Trump reference data and tests (direct + _byId)
- Add Trump _byId test to TestLiveByNickname
