refactor(traffic): update traffic flow host file generation and configuration scripts

- Renamed and refactored functions for better clarity, including `buildHostComposeSnippet` to `buildHostComposeOverride` and `buildHostNftSnippet` to `buildHostLinuxInstallSh`.
- Introduced a new script for Linux installation of WireGuard, enhancing the setup process for Docker hosts.
- Updated the `generateNativeConf` function to conditionally include the listen port in the configuration.
- Adjusted the `FlowOverlaySheet` component to default to the new Linux tab and improved the user interface for selecting jump-hosts.
