[Bug]: Align send_message signature for BaseClient and Client

What happened?

The current signature of the send_message method, differs from the Client interface

Lines 111 to 117 in d2d3860

    
           async def send_message( 
        
               self, 
        
               request: Message, 
        
               *, 
        
               context: ClientCallContext | None = None, 
        
               request_metadata: dict[str, Any] | None = None, 
        
               extensions: list[str] | None = None,

and the BaseClient implementation

a2a-python/src/a2a/client/base_client.py

Lines 62 to 69 in d2d3860

    
           async def send_message( 
        
               self, 
        
               request: Message, 
        
               *, 
        
               configuration: MessageSendConfiguration | None = None, 
        
               context: ClientCallContext | None = None, 
        
               request_metadata: dict[str, Any] | None = None, 
        
               extensions: list[str] | None = None,

Code of Conduct

I agree to follow this project's Code of Conduct

I’d like to work on this.

Proposed Solution:
I will align the send_message signature in src/a2a/client/client.py with the BaseClient implementation by adding the configuration: MessageSendConfiguration | None = None keyword-only argument. I will also ensure that MessageSendConfiguration is correctly imported in the abstract class to maintain type-hint consistency.

Please assign this to me.
