🎨 Palette: Add context tooltips to financial inputs

[aarjava]

💡 What: Added help tooltips to key statistical and financial parameter inputs in the sidebar.
🎯 Why: Financial applications use domain-specific jargon (e.g., lookback windows, ADV, basis points) that can be confusing for users. Adding concrete examples directly inline provides clarity and context.
♿ Accessibility: Increases comprehension for users unfamiliar with standard parameter constraints.
