feat: DBIS GRU bridge volume (dfio_meta_main + Ethereum)

[defiQUG]

Summary

Adds DBIS GRU bridge volume tracking for Defi Oracle Meta (chain 138) hub escrow and Ethereum cW L2 mint/burn.

• Hub: CWMultiTokenBridgeL1 — Locked (deposit into bridge), Released (withdrawal)
• Mainnet L2: CWMultiTokenBridgeL2 — Minted / Burned

This is bridge flow volume, not TVL. Locked collateral TVL is tracked separately via DefiLlama-Adapters#19386. DODO PMM pool TVL: DefiLlama-Adapters#19198 (merged).

Token disclosure

c* tokens are GRU compliant eMoney on Chain 138 — not Circle USDC or Tether USDT products. cW* are wrapped mirrors on public chains.

Upstream blockers

1. Add dfio_meta_main to @defillama/sdk Chain + RPC env (DFIO_META_MAIN_RPC, chainId 138).
2. Confirm chainCoingeckoIds for hub chain (pairs with defillama-server#12094 coin mappings).
3. Assign defillamaId when protocol row exists (currently null in bridgeNetworkData).

Test plan

• npm run test dbis-gru 2000 with DFIO_META_MAIN_RPC + ETHEREUM_RPC in .env.test
• npm run test-txs <start> <end> dbis-gru returns non-empty daily volume for active period
• No double-count with existing CCIP adapter (we filter DBIS contract addresses only)
