Administrator 14893e62a5 feat: Geutebruck GeViScope/GeViSoft Action Mapping System - MVP 
This MVP release provides a complete full-stack solution for managing action mappings
in Geutebruck's GeViScope and GeViSoft video surveillance systems.

## Features

### Flutter Web Application (Port 8081)
- Modern, responsive UI for managing action mappings
- Action picker dialog with full parameter configuration
- Support for both GSC (GeViScope) and G-Core server actions
- Consistent UI for input and output actions with edit/delete capabilities
- Real-time action mapping creation, editing, and deletion
- Server categorization (GSC: prefix for GeViScope, G-Core: prefix for G-Core servers)

### FastAPI REST Backend (Port 8000)
- RESTful API for action mapping CRUD operations
- Action template service with comprehensive action catalog (247 actions)
- Server management (G-Core and GeViScope servers)
- Configuration tree reading and writing
- JWT authentication with role-based access control
- PostgreSQL database integration

### C# SDK Bridge (gRPC, Port 50051)
- Native integration with GeViSoft SDK (GeViProcAPINET_4_0.dll)
- Action mapping creation with correct binary format
- Support for GSC and G-Core action types
- Proper Camera parameter inclusion in action strings (fixes CrossSwitch bug)
- Action ID lookup table with server-specific action IDs
- Configuration reading/writing via SetupClient

## Bug Fixes
- **CrossSwitch Bug**: GSC and G-Core actions now correctly display camera/PTZ head parameters in GeViSet
- Action strings now include Camera parameter: `@ PanLeft (Comment: "", Camera: 101028)`
- Proper filter flags and VideoInput=0 for action mappings
- Correct action ID assignment (4198 for GSC, 9294 for G-Core PanLeft)

## Technical Stack
- **Frontend**: Flutter Web, Dart, Dio HTTP client
- **Backend**: Python FastAPI, PostgreSQL, Redis
- **SDK Bridge**: C# .NET 8.0, gRPC, GeViSoft SDK
- **Authentication**: JWT tokens
- **Configuration**: GeViSoft .set files (binary format)

## Credentials
- GeViSoft/GeViScope: username=sysadmin, password=masterkey
- Default admin: username=admin, password=admin123

## Deployment
All services run on localhost:
- Flutter Web: http://localhost:8081
- FastAPI: http://localhost:8000
- SDK Bridge gRPC: localhost:50051
- GeViServer: localhost (default port)

<p xmlns="http://www.w3.org/TR/REC-html40">To make the usage of the native Win32 DLLs
easier in .NET languages like C# or VB.NET, the SDK contains some wrapper
assemblies around the plain SDK DLLs.

<p xmlns="http://www.w3.org/TR/REC-html40">The SDK provides wrapper assemblies for the .NET-Frameworks versions 2.0 and 4.0 which are named as follows:</p>

<p xmlns="http://www.w3.org/TR/REC-html40">These wrapper assemblies can be used
together with our native SDK DLLs (GscActions.DLL, GscDBI.DLL, GscHelper.DLL,
GscMediaPlayer.DLL, MscDBI.DLL) to create custom applications under any .NET
language on a windows platform. The assemblies need to be referenced by the
.NET project and all the files (assemblies and native DLLs) have to reside in
the application folder.

that uses the .NET wrapper contained in the SDK, the following prerequisites
have to be fulfilled:
</p>
<p xmlns="http://www.w3.org/TR/REC-html40">&#160;</p>
<p class="GutZuWissenHeader" xmlns="http://www.w3.org/TR/REC-html40">a) Microsoft Visual C++ Redistributable Package has to be
installed</p>
<p xmlns="http://www.w3.org/TR/REC-html40"> <![CDATA[ ]]></p>
<p xmlns="http://www.w3.org/TR/REC-html40">The wrapper assemblies are developed in C++/CLI. So for executing them on a none development machine, the Microsoft Visual C++ Redistributable Package is needed. This package exists in a debug or in a release version. On productive machines the release version needs to be installed.</p>
<p xmlns="http://www.w3.org/TR/REC-html40">&#160;</p>
<p xmlns="http://www.w3.org/TR/REC-html40">For applications using the .NET-Framework 2.0 the Visual C++ 2008 Redistributable Package is needed. In case that the application is developed using the .NET-Framework 4.0 you need to install the Visual C++ 2010 Redistributable Package.</p>
<p xmlns="http://www.w3.org/TR/REC-html40"> <![CDATA[ ]]></p>
<p class="GutZuWissenHeader" xmlns="http://www.w3.org/TR/REC-html40">b) .NET Framework Version 2.0 SP 1 or newer has to be
installed </p>
<p xmlns="http://www.w3.org/TR/REC-html40">&#160;</p>
<p xmlns="http://www.w3.org/TR/REC-html40">If updating the .NET Framework on a
GEUTEBRÜCK device (GeViScope or re_porter) fails, a special Microsoft tool
Windows Installer CleanUp Utility (MSICUU2.exe) can improve the situation. After executing
this tool, updating the Framework should be possible.

<p xmlns="http://www.w3.org/TR/REC-html40">&#160; </p>
<p class="GutZuWissenHeader" xmlns="http://www.w3.org/TR/REC-html40">c) Wrapper assemblies AND native SDK DLLs are needed </p>

<p xmlns="http://www.w3.org/TR/REC-html40">Beside the custom application also the
wrapper assemblies and the native SDK DLLs (listed above) are needed in the
same folder as in which the custom application resides.
</p>
<p xmlns="http://www.w3.org/TR/REC-html40">&#160;</p>
<p xmlns="http://www.w3.org/TR/REC-html40">If the application uses the .NET-Framework 4.0 you need to reference the GeViScope wrapper DLLs with the extension _4_0 otherwise please use the wrapper assemblies with the extension _2_0 (see above).</p>
