fix: sidebar layout, copilot auth script, config setup

- Sidebar uses absolute inset-0 with overflow-y-auto for proper scrolling
- Border moved to inner div so it hides with sidebar
- Copilot auth script uses portable sed instead of grep -P (macOS compat)
- dispatch.toml with 3 keys, 4 models, fallback order
- .env.dispatch with key placeholders and script reference
- docker-compose loads .env.dispatch via env_file
