chore(streamlit): migrate components.v1.html → st.iframe (deprecation)

Browse Source 
Streamlit logs a deprecation notice on every render:

  Please replace ``st.components.v1.html`` with ``st.iframe``.
  ``st.components.v1.html`` will be removed after 2026-06-01.

Replace all 9 call sites (6 tool pages + 3 in ``_legacy.py``).
Both APIs feed ``srcdoc`` to the underlying iframe so the
HTML/JS payload and the cross-frame DOM access pattern
(``window.parent.document``) are unchanged.

``st.iframe`` rejects ``height=0`` (raises ``StreamlitInvalid
HeightError``), so bump every zero-height call to ``height=1``.
1px is effectively invisible — these are script-only iframes, no
visible payload — and avoids the validator.

This bypasses every Streamlit container.
