feat: GeViScope SDK integration with C# Bridge and Flutter app
- Add GeViScope Bridge (C# .NET 8.0) on port 7720 - Full SDK wrapper for camera control, PTZ, actions/events - 17 REST API endpoints for GeViScope server interaction - Support for MCS (Media Channel Simulator) with 16 test channels - Real-time action/event streaming via PLC callbacks - Add GeViServer Bridge (C# .NET 8.0) on port 7710 - Integration with GeViSoft orchestration layer - Input/output control and event management - Update Python API with new routers - /api/geviscope/* - Proxy to GeViScope Bridge - /api/geviserver/* - Proxy to GeViServer Bridge - /api/excel/* - Excel import functionality - Add Flutter app GeViScope integration - GeViScopeRemoteDataSource with 17 API methods - GeViScopeBloc for state management - GeViScopeScreen with PTZ controls - App drawer navigation to GeViScope - Add SDK documentation (extracted from PDFs) - GeViScope SDK docs (7 parts + action reference) - GeViSoft SDK docs (12 chunks) - Add .mcp.json for Claude Code MCP server config Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
