Summary: Stock Unlock adds fair value calculator section

Why It Matters: The site is moving from just "scoring" stocks to helping users calculate a specific dollar value for them. This targets investors who want to know if a stock is currently over or underpriced.

What Changed:

• Added a new section titled "What's a stock actually worth?"
• Introduced a fair value calculator that pre-fills financial data.
• Added text explaining that users can customize assumptions to find a stock's value.
• Expanded the security section at the bottom to clarify that they cannot move funds or execute trades.
• Added explicit mentions of data encryption and "one-click" brokerage disconnection.
