feat: deposit/withdraw via HyperUnit bridge + bridge-status
- fintool deposit <amount> ETH/BTC/SOL — generates Unit deposit address on native chain - fintool withdraw <amount> ETH/BTC/SOL --to <addr> — generates Unit withdrawal address on HL - fintool bridge-status — shows all Unit operations for the wallet - USDC deposits/withdrawals route to HL's native Arbitrum bridge with instructions - Fee estimation from Unit API - Minimum amount validation per asset
