Python: fix(python): preserve replayed approval calls

[HUAN2022A]

Motivation & Context

Fixes #7304. A completed function call can share a call_id with a later replayed approval request. The previous global deduplication treated the earlier result as answering every occurrence of that id, which restored the request as a third orphaned function call.

Description & Review Guide

• What are the major changes? Track pending function calls in message order while replacing approval content, and add a regression test for a completed call followed by a replayed call with the same id.
• What is the impact of these changes? Approval replay no longer produces an unmatched duplicate function call when call ids are reused.
• What do you want reviewers to focus on? The ordering behavior for reused call ids and the existing placeholder-result handling.

Pull request overview

This PR fixes a Python transcript-rewrite edge case in approval replay handling where a previously completed tool call can reuse a call_id and cause _replace_approval_contents_with_results to incorrectly restore an extra orphaned function_call. The update makes pending-call tracking order-aware so that call-id reuse after completion doesn’t confuse deduplication.

Changes:

• Update _replace_approval_contents_with_results to track pending call_ids in message order by adding on function_call and removing on non-placeholder function_result.
• Add a regression test covering a completed call followed by a replayed call + approval request reusing the same call_id.

Thank you @HUAN2022A for investigating the reused-call-id replay case and proposing the ordered pending-call fix. Draft PR #7345 incorporates that scenario and extends it to multiple completed/replayed rounds, placeholders, rejected calls, and exactly-once replay. Closing this PR as superseded so the review can continue on the consolidated change.
