Remove concrete Conversations cast to enable DI of IConversations implementations

[Copilot]

Two locations in the codebase cast IConversations to the concrete Conversations class to call GetConversationMemberAsync, preventing dependency injection of custom implementations.

Changes

Added missing interface method

• Added GetConversationMemberWithHttpMessagesAsync(string userId, string conversationId, ...) to IConversations interface
• Added corresponding GetConversationMemberAsync extension method for IConversations

Removed concrete casts

• TeamsInfo.GetMemberAsync: ((Conversations)connectorClient.Conversations).GetConversationMemberAsync(...) → connectorClient.Conversations.GetConversationMemberAsync(...)
• SkillHandlerImpl.OnGetMemberAsync: ((Conversations)client.Conversations).GetConversationMemberAsync(...) → client.Conversations.GetConversationMemberAsync(...)

Updated test mocks

• Implemented new interface method in MemoryConversations

Before/After

// Before - forced to use concrete implementation
var member = await ((Conversations)connectorClient.Conversations)
    .GetConversationMemberAsync(userId, conversationId, cancellationToken);

// After - works with any IConversations implementation
var member = await connectorClient.Conversations
    .GetConversationMemberAsync(userId, conversationId, cancellationToken);

This enables custom adapter implementations and test mocks to provide their own IConversations implementations without being forced to inherit from the concrete Conversations class.

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
