feat: Fine-tune trading UI with coin dropdown selection

- Remove simulation mode and quick USDC swap sections
- Replace trading pairs with two dropdown fields (From → To)
- Add coin selection for perpetuals with leverage
- Enhanced UX with coin swap button and dynamic labels
- Always use real Jupiter DEX execution

- 7 supported coins: SOL, USDC, USDT, BTC, ETH, RAY, ORCA
- Intuitive From/To dropdowns for spot trading
- Dedicated perpetual coin selection
- Real-time label updates based on selection

- Removed confusing simulation/real toggle
- Streamlined execution always via Jupiter DEX
- Cleaner UI focused on real trading
- Better risk warnings for actual trades

 Tested:
- Real SOL→USDC swap: TX 59QpmZWFnuHFNCVKujaq9tyJThy3fFTHpPSrug2vPQHYnE1Mk33wfwgHbc3oaW8E6m7kH8K7xpExESdV73LSqLT9
- Perpetual position: SOL 5x leverage simulation ready
- All APIs working correctly in Docker Compose v2
