refactor(vscode-ide-companion): clean up code and improve type safety

- Remove commented out error handling code in acpMessageHandler
- Simplify session update handler by removing redundant comments
- Clean up chat types interface definitions
- Simplify null check in MessageRouter
- Improve type safety in SettingsMessageHandler with ApprovalModeValue type
