Fix back view: show whenever movingUp, not just during walk anim

Remove scripted conversation fallbacks — LLM-only conversations

- drawPerson: change `if (walkAnim && movingUp)` to `if (movingUp)` so
the back view persists as the agent's facing direction, matching how
horizontal facing is maintained when standing still
- conversation.py: revert scripted starters/replies; if LLM is
unavailable initiate_conversation returns None and continue_conversation
ends the exchange — no canned dialogue
