alliscode 1baf4af4d8 Hosted-agent HITL: persist session across previous_response_id chains; run approved local AIFunctions
Two regressions hit declarative workflows that use require_approval=true when
the client chains turns via previous_response_id (no conversation_id):

1. AgentFrameworkResponseHandler keyed the AgentSession store solely on
   conversation_id, so when only previous_response_id was present the
   StateBag (which holds ToolApprovalIdMap) was discarded after each turn.
   The next turn then threw 'No approval mapping recorded for wire id ...'
   in InputConverter.ConvertMcpApprovalResponse.

   Fix: fall back to previous_response_id on load and to context.ResponseId
   on save so the response-id chain becomes a valid session key. Conversation
   id remains preferred when present.

2. InvokeFunctionToolExecutor.CaptureResponseAsync only acted on
   FunctionResultContent. In the hosted Foundry path the approval response
   arrives as a ToolApprovalResponseContent with no FunctionResultContent,
   so the local AIFunction never ran and downstream PropertyPath/SendActivity
   consumers (e.g. {Local.RefundResult}) saw empty values.

   Fix: when no FunctionResultContent matches but an approved
   ToolApprovalResponseContent does, look up the registered AIFunction by
   name on agentProvider.Functions and invoke it with the evaluated
   arguments, surfacing the result through the existing assignment path.
