fix(mystery): persist player input lines so they survive reload

appendLines() only updated the DOM, never state.transcript, so any
UI-originated line (player input, restart/undo/quit messages) vanished
on page reload. Engine narration was unaffected because dispatch()
already adds its lines to state.transcript.

Fix: appendLines() now pushes into state.transcript (capped at
TRANSCRIPT_CAP) and renders. Engine output uses renderAll() directly
since dispatch already added its lines to state.
