Port the rebased diagnostics and session logging onto the modules

origin/main landed replayable session logging (MessageHistoryRecorder), file
logging (ApplicationFileLogging) and a user-list refresh split on the old flat
layout. The rebase carried the new files, but three things needed the new
architecture:

- ChatController.fireUserListUpdate() used javafx Platform; core is toolkit-free
  now, so it dispatches through uiDispatcher like every other fire method.
- Two new tests were left in the old src/test/java; moved into core.
- ScoreServiceRefreshTest mocked javafx Platform statically; it now injects the
  DirectUiDispatcher the no-arg constructor installs.

The Leaflet map performance work was dropped with the HTML map it optimised.

classes testClasses and test are green: 1069 tests, 0 failures, 3 skipped.
