Add documentation for Exporters and Web Interface in local client

- Created a new documentation page for Exporters detailing configuration options for Home Assistant, MQTT, VictoriaMetrics, Prometheus, and Jeedom.
- Added an overview of common functionalities such as connection testing, saving configurations, and resetting to defaults.
- Introduced a new Web Interface documentation page outlining access, available pages, navigation, and configuration options.
- Highlighted differences between the local client and the gateway, emphasizing the local data storage and the absence of user account management in the local client.
