feat(evm-exec): add FOMO fee collectors BSC/Base

[Flotapponnier]

Summary

• Add FOMO BSC fee collector 0x99748cbd931cb367dad265c5b2b4bd306d448e99 (confirmed 100% via relay-fomo on-chain tag + tx amount sample)
• Add FOMO Base fee collector 0x8f10b468b06c6fd214b65f87778827f7d113f996 (ERC1967Proxy splitter, confirmed via Dune trace analysis, ~70% confidence — monitors 100% gross fee flow)
• Both addresses discovered via Dune trace queries filtering on relay-fomo calldata tag (0x72656c61792d666f6d6f)
• BSC: NativeEnabled=true (BNB fees 0.003–0.29 BNB/tx confirmed); Base: NativeEnabled=false (no free trace API, USDC only)

Validation

Validated by two independent AI analyses before adding. BSC address confirmed contract (fee router/splitter pattern), Base address is ERC1967Proxy receiving 216 ETH across 2567 txs.

Test plan

• VPS rsync + docker rebuild on ocb-par-main
• Check collector logs for FOMO ingestion after bootstrap

Revert: BSC address 0x99748cbd is TychoRouter (Propellerheads DEX aggregator), not FOMO fee wallet. DeFiLlama confirms FOMO is Solana-only. EVM fee addresses unconfirmed — removing until verified via direct trade trace.

Updated with correct address: 0x9fc4e320a181e88644a302d11f1f158ef0699e37 (Gnosis Safe multisig, confirmed via Relay API appFees field — 30/37 fee-bearing requests)
