TRCLI-207 Fix test run cases deletion issue in update_run_in_plan_entry

[acuanico-tr-galt]

Issue being resolved: #372

Solution description

Fixed a critical bug where uploading JUnit XML results to existing test runs (with configs in a test plan) was failing with error: "case unknown or not part of the test run". The root cause was that trcli wasn't sending the include_all parameter when calling update_run_in_plan_entry, causing TestRail to deselect all test cases from the run.

Changes

Updated: trcli/api/api_request_handler.py (lines 471-486) changed the update_run() method to:

• Read and preserve the existing include_all setting from the run
• Only manage case_ids when include_all=False
• Remove case_ids from payload when include_all=True (cleaner API
  contract)
• Add error handling for __get_all_tests_in_run() API failures

Potential impacts

None

Steps to test

Upload JUnit results to an existing run with configs in a test plan (the original bug scenario) -> verify case existing cases are
preserved -> Test with --run-include-all runs to ensure they still work in add_run command
