Add documentation for KUKA Sunrise features and programs

- Created a new document for the Station interface, detailing its menu structure, process data, safety functions, frames, and smartPAD function buttons.
- Added a document for RobotPowerControl, explaining its purpose for safely shutting down or restarting the KUKA Sunrise Cabinet controller.
- Introduced ServerFriRos2 documentation, outlining its role in establishing an FRI connection between the KUKA LBR iiwa and a ROS 2 computer.
- Documented the TeachKuka application, which allows manual teaching of the KUKA LBR iiwa, including position capturing and trajectory recording.
- Added an overview of Sunrise Workbench, including installation instructions for Windows and Linux.
- Created a section on installing a Windows compatibility tool (PortProton) on Linux.
- Documented the installation process for SunriseWorkbench on Linux using PortProton.
- Added installation instructions for SunriseWorkbench on Windows.
- Created troubleshooting documentation for configuration errors and SSL errors during installation.
- Implemented a hook to generate the shared PDF only during the default-language build.

+# Overview
+
+**Lightweight Cobot (LWC)** is an open system for controlling the **KUKA LBR IIWA 7 R800** collaborative robot based on **ROS 2 Jazzy**. It supports both a physical robot through the FRI protocol and a virtual Webots simulation. The project includes the `cobot` CLI, a ROS 2 Control hardware interface, MoveIt 2 motion planning, and REST/MCP APIs for AI-agent integration.

+|---|---|---|
+| **GitVerse** (preferred) | [daniel-robotics/lightweight-cobot](https://gitverse.ru/daniel-robotics/lightweight-cobot) | primary |
+| GitHub | [Daniel-Robotic/lightweight-cobot](https://github.com/Daniel-Robotic/lightweight-cobot) | mirror |

+## Online documentation
+
+- [GitVerse Pages](https://daniel-robotics.gitverse.site/lightweight-cobot) — primary
+- [GitHub Pages](https://daniel-robotic.github.io/lightweight-cobot/) — mirror
+
+## Requirements
+
+- A physical **KUKA LBR IIWA 7 R800** for real-robot operation, or
+- **Webots** if you only want to use simulation;
+- A PC or server running **Ubuntu 24.04**, or SSH access to an existing server;
+- Network access to the robot controller.
+
+## Recommended order
+
+1. [**Sunrise Workbench setup**](getting-started/sunrise-setup.md) — prepare the KUKA controller. *(Physical robot only.)*
+2. [**Connect to the server**](getting-started/remote-access.md) — choose local or remote deployment and connect over SSH.
+3. [**Install the project**](getting-started/installation.md) — install LWC using `curl`, `git`, or manually, then run `cobot setup`.
+4. [**Configure the system**](getting-started/configuration.md) — set the robot IP, ports, and tools in `cobot-setting.yaml`.
+5. [**cobot CLI**](getting-started/cli-reference.md) — review commands for running, building, and updating the project.
+
+!!! tip "Simulation only?"
+    If a physical robot is unavailable, skip step 1 and start with the [project installation](getting-started/installation.md). Launch the simulator with `cobot run --simulate`.
+
+!!! info "`cobot setup` automates steps 3–4"
+    After installing the project, run `cobot setup`. The wizard will configure the documentation, robot parameters, and the ROS 2 or Docker build environment.
