Rename FlatUIState to FlatConfidenceBall

Rename the parameter key FlatUIState to FlatConfidenceBall and update all references. Changes update common/params_keys.h, the UI state property (self.flat_confidence_ball in selfdrive/ui/sunnypilot/ui_state.py), the confidence ball rendering check (selfdrive/ui/mici/onroad/confidence_ball.py), and the params metadata (sunnypilot/sunnylink/params_metadata.json) with a clearer title/description
