Krypto Kajun e99cd17956 feat: Fix critical Arbitrum transaction parsing and add DEX parameter extraction ...

BREAKING: Resolves "Block has unsupported transaction types" issue that prevented
MEV analysis by implementing raw RPC transaction parsing instead of go-ethereum.

Changes:
- Add ArbitrumL2Parser with raw RPC calls to bypass go-ethereum transaction type limitations
- Implement correct DEX function signatures for Arbitrum (38ed1739, 414bf389, ac9650d8, etc.)
- Add comprehensive swap parameter decoding (amounts, tokens, prices)
- Support Uniswap V2/V3, SushiSwap function detection
- Extract swap amounts for MEV arbitrage analysis
- Fix WebSocket + block polling dual monitoring system

Results:
- ✅ Full transaction parsing (no more "unsupported transaction types")
- ✅ DEX transactions detected with swap amounts
- ✅ MEV analysis data: AmountIn, MinOut, protocol identification
- ✅ Real-time processing: ~4 blocks/second with detailed transaction data
