"""Test harness page for ``render_findings_panel``.

A standalone Streamlit page module the AppTest layer can drive
directly. Renders the findings panel with whatever findings live in
``st.session_state["test_findings"]`` so test code can inject a list
and inspect what's rendered, without having to fake a file_uploader
widget.

Lives next to its test file so it ships with the GUI test layer and
never gets confused with a real page.
