fix: Fix test fixtures JsonDataNode constructor calls

- Add 'servers' key to mock_mcp.json (MCPClient expects this structure)
- Add 'servers' wrapper to MCPClientTests.cpp test configs
- Fix JsonDataNode constructor calls in test fixtures:
  - JsonDataNode(json) -> JsonDataNode("name", json)
  - Affected: AIModuleTests, MonitoringModuleTests, StorageModuleTests,
    VoiceModuleTests, TimeSimulator

Test results:
- Module tests: 52/60 passing (87%)
- MCP Types tests: 15/15 passing (100%)
- MCP Transport/Client: Require Python server integration fixes
