feat: Add config flow for SmartIR integration with multi-step UI wizard

- Implemented a new config flow in `config_flow.py` for SmartIR, allowing users to select platforms, controllers, and devices through a guided interface.
- Added support for new device codes in `codes_index.json` for Apton and Andersson manufacturers.
- Enhanced fan, light, and media player components to support setup from config entries.
- Introduced `strings.json` and `translations/en.json` for improved localization of the configuration steps.
- Created a tool `build_index.py` to rebuild the `codes_index.json` from individual device JSON files.
- Updated `smartir_capture.py` to handle single-code modes and excluded modes for better device configuration.
- Added `iot_class` and `config_flow` attributes in `manifest.json` to support the new configuration flow.
