Reported: uploading multiple files on the home page and clicking Run
analysis blew up with
StreamlitDuplicateElementKey: key='_findings_open_02_text_cleaner'
when two uploaded files both had Clean Text findings.
Root cause: ``render_findings_panel`` is invoked once per uploaded
file from ``_home.py``, but the per-tool jump button used a
filename-agnostic key:
key=f"_findings_open_{tool_id}"
Two files both flagging Clean Text → two buttons with identical keys
→ Streamlit rejects the second one.
Fix:
- Add ``key_namespace: str = ""`` to ``render_findings_panel``. The
helper hashes it (sha1 truncated to 8 chars) and appends to every
button key, so different namespaces produce different keys but the
same namespace stays stable across reruns.
- The home page now passes the filename:
``render_findings_panel(findings, header=f"📄 {name}", key_namespace=name)``.
- The single-call site in ``upload_and_analyze_section`` (the legacy
helper, only used outside the new home-page path) keeps the default
empty namespace, which is fine because that path renders findings
for ONE file at a time.
