Implement Server CRUD with bool type fix and auto-increment IDs

CRITICAL FIX: Changed boolean fields from int32 to bool type - Enabled, DeactivateEcho, DeactivateLiveCheck now use proper bool type (type code 1) - Previous int32 implementation (type code 4) caused servers to be written but not recognized by GeViSet - Fixed field order to match working reference implementation Server CRUD Implementation: - Create, Read, Update, Delete operations via gRPC and REST API - Auto-increment server ID logic to prevent conflicts - Proper field ordering: Alias, DeactivateEcho, DeactivateLiveCheck, Enabled, Host, Password, User Files Added/Modified: - src/sdk-bridge/GeViScopeBridge/Services/ConfigurationServiceImplementation.cs (bool type fix, CRUD methods) - src/sdk-bridge/Protos/configuration.proto (protocol definitions) - src/api/routers/configuration.py (REST endpoints) - src/api/protos/ (generated protobuf files) - SERVER_CRUD_IMPLEMENTATION.md (comprehensive documentation) Verified: - Servers persist correctly in GeViSoft configuration - Servers visible in GeViSet with correct boolean values - Action mappings CRUD functional - All test scripts working (server_manager.py, cleanup_to_base.py, add_claude_test_data.py) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>

+# Server CRUD Implementation
+
+## Overview
+
+Full CRUD (Create, Read, Update, Delete) implementation for GeViSoft G-Core server management via gRPC SDK Bridge and REST API.
+
+## Critical Implementation Details
+
+### Boolean Type Fix
+
+**Issue**: Initial implementation used `int32` type for boolean fields (Enabled, DeactivateEcho, DeactivateLiveCheck), causing servers to be written but not recognized by GeViSet.
+
+**Solution**: Changed to proper `bool` type (type code 1) instead of `int32` (type code 4).
+
+**Affected Files**:
+- `src/sdk-bridge/GeViScopeBridge/Services/ConfigurationServiceImplementation.cs`
+  - Lines 1062-1078: CreateServer method
+  - Lines 1194-1200: UpdateServer method
+  - Lines 1344-1383: UpdateOrAddChild helper (added bool handling)
+
+### Field Order Requirements
+
+Server configuration nodes must have fields in specific order:
+1. Alias (string)
+2. DeactivateEcho (bool)
+3. DeactivateLiveCheck (bool)
+4. Enabled (bool)
+5. Host (string)
+6. Password (string)
+7. User (string)
+
+**Reference**: Working implementation in `C:\DEV\COPILOT_codex\geviset_parser.py` lines 389-404
+
+### Auto-Increment Server IDs
+
+**Implementation**: `server_manager.py` demonstrates proper ID management:
+- Reads existing servers from configuration
+- Finds highest numeric server ID
+- Increments by 1 for new server ID
+- Skips non-numeric IDs gracefully
+
+```python
+def get_next_server_id(servers):
+    numeric_ids = []
+    for server in servers:
+        try:
+            numeric_ids.append(int(server['id']))
+        except ValueError:
+            pass
+    if not numeric_ids:
+        return "1"
+    return str(max(numeric_ids) + 1)
+```
+
+## API Endpoints
+
+### REST API (FastAPI)
+
+**Base Path**: `/api/v1/configuration`
+
+- `GET /servers` - List all G-Core servers
+- `GET /servers/{server_id}` - Get single server by ID
+- `POST /servers` - Create new server
+- `PUT /servers/{server_id}` - Update existing server
+- `DELETE /servers/{server_id}` - Delete server
+
+**Implementation**: `src/api/routers/configuration.py` lines 278-460
+
+### gRPC API
+
+**Service**: `ConfigurationService`
+
+Methods:
+- `CreateServer(CreateServerRequest)` → `ServerOperationResponse`
+- `UpdateServer(UpdateServerRequest)` → `ServerOperationResponse`
+- `DeleteServer(DeleteServerRequest)` → `ServerOperationResponse`
+- `ReadConfigurationTree()` → Configuration tree with all servers
+
+**Implementation**: `src/sdk-bridge/GeViScopeBridge/Services/ConfigurationServiceImplementation.cs`
+
+## Server Data Structure
+
+```protobuf
+message ServerData {
+    string id = 1;                      // Server ID (numeric string recommended)
+    string alias = 2;                   // Display name
+    string host = 3;                    // IP address or hostname
+    string user = 4;                    // Username (default: "admin")
+    string password = 5;                // Password
+    bool enabled = 6;                   // Enable/disable server
+    bool deactivate_echo = 7;           // Deactivate echo (default: false)
+    bool deactivate_live_check = 8;     // Deactivate live check (default: false)
+}
+```
+
+## Test Scripts
+
+### Production Scripts
+
+1. **server_manager.py** - Complete server lifecycle management
+   - Lists existing servers
+   - Auto-increments IDs
+   - Creates, deletes servers
+   - Manages action mappings
+   - Cleanup functionality
+
+2. **cleanup_to_base.py** - Restore configuration to base state
+   - Deletes test servers (2, 3)
+   - Preserves original server (1)
+   - Quick reset for testing
+
+3. **add_claude_test_data.py** - Add test data with "Claude" prefix
+   - Creates 3 servers: Claude Server Alpha/Beta/Gamma
+   - Creates 2 action mappings
+   - All identifiable by "Claude" prefix
+
+4. **check_and_add_mapping.py** - Verify and add action mappings
+   - Lists existing Claude mappings
+   - Adds missing mappings
+   - Ensures complete test data
+
+### Legacy Test Scripts
+
+- `test_server_creation.py` - Direct gRPC server creation test
+- `add_server_and_mapping.py` - Combined server and mapping creation
+
+## Verification Process
+
+### Testing Workflow
+
+1. **Start Services**:
+   ```bash
+   cd C:\GEVISOFT
+   start GeViServer.exe console
+
+   cd C:\DEV\COPILOT\geutebruck-api\src\sdk-bridge\GeViScopeBridge\bin\Debug\net8.0
+   start GeViScopeBridge.exe
+   ```
+
+2. **Run Test Script**:
+   ```bash
+   python server_manager.py
+   ```
+
+3. **Stop Services** (required before GeViSet connection):
+   ```powershell
+   Stop-Process -Name GeViScopeBridge -Force
+   Stop-Process -Name python -Force
+   Stop-Process -Name GeViServer -Force
+   ```
+
+4. **Verify in GeViSet**:
+   - Connect to GeViServer
+   - Check Configuration → GeViGCoreServer
+   - Verify servers appear with correct bool values
+
+### Known Issues & Solutions
+
+**Issue**: Port 50051 (gRPC) in use
+- **Solution**: Stop SDK Bridge process
+
+**Issue**: SetupClient connection refused (Error 307)
+- **Cause**: GeViSet already connected (only one SetupPort client allowed)
+- **Solution**: Disconnect GeViSet, retry SetupClient
+
+**Issue**: Servers created but not visible in GeViSet
+- **Root Cause**: Using int32 instead of bool type
+- **Solution**: Use proper bool type as documented above
+
+## Action Mapping CRUD
+
+Action mappings can also be managed via the same ConfigurationService.
+
+**Endpoints**:
+- `GET /api/v1/configuration/action-mappings` - List all mappings
+- `GET /api/v1/configuration/action-mappings/{mapping_id}` - Get single mapping
+- `POST /api/v1/configuration/action-mappings` - Create mapping
+- `PUT /api/v1/configuration/action-mappings/{mapping_id}` - Update mapping
+- `DELETE /api/v1/configuration/action-mappings/{mapping_id}` - Delete mapping
+
+**Note**: Mapping IDs are 1-based ordinal positions in the MappingRules list.
+
+## Dependencies
+
+- GeViServer must be running
+- SDK Bridge requires GeViServer connection
+- REST API requires SDK Bridge on localhost:50051
+- GeViSet requires exclusive SetupPort (7703) access
+
+## Success Metrics
+
+✅ Servers persist correctly in GeViSoft configuration
+✅ Servers visible in GeViSet with correct boolean values
+✅ Auto-increment ID logic prevents conflicts
+✅ All CRUD operations functional via gRPC and REST
+✅ Action mappings create, read, update, delete working
+✅ Configuration changes survive GeViServer restart
