🎨 Palette: Add helpful tooltips to complex statistical parameters

[aarjava]

💡 What: Added help tooltips with concrete examples to complex financial and statistical input widgets (st.slider and st.number_input) in the sidebar.
🎯 Why: Users often struggle to map raw numerical configurations like quantiles (e.g., 0.75) or basis points (e.g., 10) to real-world expectations without explicit conversions. This adds an immediate layer of clarity to the research parameters.
📸 Before/After: Visual changes consist of standard Streamlit ? tooltips appearing next to the relevant labels on hover.
♿ Accessibility: Improves cognitive accessibility by providing concrete examples for abstract numerical inputs.
