RI-7632: initial implementation of v2 api client

[ArtemHoruzhenko]

What

This PR implements the initial support for RDI API v2 client with automatic version detection and graceful fallback to v1.

Changes

New Features

1. ApiV2RdiClient - New client implementation for RDI API v2

• Extends ApiRdiClient (v1) to inherit existing functionality
• Implements getInfo() method to retrieve RDI instance information
• Implements selectPipeline() method to automatically select the first available pipeline
• Adds support for v2-specific endpoints (/api/v2/info, /api/v2/pipelines)

2. Smart Client Factory - Enhanced RdiClientFactory with version detection

• Attempts to create v2 client first by calling getInfo() endpoint
• If v2 API is available: initializes v2 client with connect() and selectPipeline()
• If v2 API is unavailable: gracefully falls back to v1 client
• Ensures backward compatibility with existing RDI instances

New Models & Types

• RdiInfo - Model for RDI instance information (version)
• GetInfoResponse - Response type for /api/v2/info endpoint
• GetPipelinesResponse - Response type for /api/v2/pipelines endpoint
• PipelineResponses - Interface for pipeline data structure
• RdiUrlV2 - Constants for v2 API endpoints

Documentation

• Added comprehensive JSDoc comments for getInfo() and selectPipeline() methods
• Documented parameters, return types, exceptions, and usage examples

Tests

1. ApiV2RdiClient Tests (api.v2.rdi.client.spec.ts)

• 10 tests covering getInfo() and selectPipeline() methods
• Tests for success cases, error handling, and edge cases (null/undefined/empty data)
• Validates proper transformation of API responses to model instances

2. RdiClientFactory Tests (enhanced rdi.client.factory.spec.ts)

• 5 tests covering v2 client creation and v1 fallback scenarios
• Tests for version detection logic
• Tests for graceful degradation when v2 is unavailable
• Tests for error handling in both v2 and v1 flows
