fix v1.31.1: room card interactions no longer feed the active markup tool

- _markupClick ignores clicks originating from .roomlabel/.rlhandle
  (composedPath) and anything during an active drag/resize
- smoke_card_tool_conflict.mjs (draw/delroom/handle/during-resize +
  normal stage click still works); TESTING/CHANGELOG same-commit
