[Server] Extend MasterNodeManager with support for ReadAsync, WriteAsync, HistoryReadAsync, HistoryWriteAsync, TranslateBrowsePathAsync, ConditionRefreshAsync

[romanett]

Proposed changes

Extend MasterNodeManager with support for

• ReadAsync
• WriteAsync
• HistoryReadAsync
• HistoryWriteAsync
• TranslateBrowsePathAsync,
• ConditionRefreshAsync
• BrowseAsync
• BrowseNextAsync

A base implementation in the NodeManager layer will follow at a later point in time with a CustomNodeManager3, when the IAsyncNodeManager Interface is complete.

Pull Request Overview

This PR extends the MasterNodeManager with asynchronous support for several key OPC UA operations, introducing async methods for ReadAsync, WriteAsync, HistoryReadAsync, HistoryWriteAsync, TranslateBrowsePathAsync, and ConditionRefreshAsync. This modernizes the codebase by adding async capabilities while maintaining backward compatibility.

Key changes:

• Adds new async-capable interfaces for individual operations
• Extends MasterNodeManager to support both sync and async execution paths
• Implements proper async/await patterns with cancellation token support
• Creates an adapter pattern to allow existing synchronous node managers to work with the async infrastructure
