fix: Set HOME environment to /app for Ollama container

- Set HOME=/app to ensure Ollama uses /app/.ollama instead of /.ollama
- Add proper error handling and debugging in startup script
- Change working directory to /app before running Ollama commands
- Ensure proper ownership and permissions for Ollama data directory
