feat: Enhance API and Outbound Tracking Functionality

- Add test for fallback to bot account in platform IO route metadata when context message is absent.
- Improve PlatformIOManager to avoid duplicate driver entries and streamline fallback driver handling.
- Refactor OutboundTracker to support tracking by both internal message ID and driver ID, enhancing the uniqueness of pending records.
- Introduce dynamic API capabilities in RuntimeComponent, allowing plugins to replace their dynamic API lists.
- Update APIRegistry to manage dynamic APIs more effectively, including registration and toggling of API statuses.
- Implement authorization checks for dynamic API capabilities to ensure proper permissions.
- Restrict direct calls to certain host RPC methods from plugins for enhanced security.
- Refactor send_service to ensure fallback to current platform account when no context message is available.
