[CLI MCP] MCP server generates deprecated Ignite UI React module registrations

[viktorkombov]

Description:
When using Claude Sonnet with MCP server for a React app, the generated code includes deprecated module registrations:

IgrGridModule.register();
IgrPaginatorModule.register();

These are no longer required in recent Ignite UI for React versions.

Expected:
Do not include deprecated .register() calls.

Actual:
Deprecated module registrations are added to the generated code.

To resolve this all react sample should be updated not to use deprecated modules.
