fix(client): resolve WASD freezes, warnings, and chime spam

- bug_report_dialog: release_focus() before queue_free() prevents
  stale focus on ModalLayer blocking input to lower layers
- dialogue_box: clear dialogue_active immediately on conversation
  end instead of holding for entry_lifetime
- main.gd: permanent entity ID tracking per room stops recognition
  chime re-triggering when NPCs oscillate in/out of fog queue
- audio_manager: correct path res://audio/ to res://assets/audio/
- world_radial.tscn: anchors_preset 15 to 0 (script sets size)
- bug_report_dialog: push_warning to print (informational)
- debug_overlay: max() to maxi() for integer line count
- monologue_display: remove unnecessary Tween cast
