Pressure validation indexes Series as DataFrame

The new validation uses st.edited_dfTP['Pressure (bara)'], but st.edited_dfTP is produced by st.data_editor(st.session_state.tp_data['Pressure (bara)'].dropna()...) and remains a Series without a Pressure (bara) column. Accessing it with a column label raises a KeyError before the Run handler executes, so the hydrate calculation now crashes on every run even with valid pressures. Pass a DataFrame into data_editor or validate the Series directly.
