feat: Implement comprehensive DeFi platform in Digital Assets dashboard

Add a complete DeFi platform with the following features: - Tabbed interface for different DeFi functionalities - Lending & Borrowing system with APY calculations - Liquidity Pools with LP token rewards - Staking options for tokens and digital assets - Token Swap interface with real-time exchange rates - Collateralization system for loans and synthetic assets - Interactive JavaScript functionality for real-time calculations This enhancement provides users with a complete suite of DeFi tools directly integrated into the Digital Assets dashboard.
