Migrate from is_context_in_segment to get_evaluation_result (engine context-value) #6669
Description
Context
As part of the flag-engine v10 migration (PR #6653), we vendored is_context_in_segment from the fix/missing-export branch. However, is_context_in_segment is not part of flag-engine's public API anymore.
Task
Switch from is_context_in_segment to get_evaluation_result.
