feat(chains): add Zetrix L2 Testnet (chainId 938748)

[armmarov]

What

Adds Zetrix L2 Testnet (EVM, chainId 938748, native currency ZETRIX2, 18 decimals) to the supported-chains registry so TrustVC-based issuers/verifiers can validate transferable records (eBL) issued on the chain out of the box, without a runtime registerChain shim.

Changes

• src/utils/supportedChains/index.ts — CHAIN_ID.zetrixL2Testnet = '938748' + SUPPORTED_CHAINS entry (label, type test, currency ZETRIX2, RPC, explorer, nativeCurrency).
• src/utils/network/index.ts — add zetrixL2Testnet to networks and ZETRIX2 to networkCurrency.
• src/utils/static/icons.ts — chain icon (currently a placeholder SVG; happy to swap in the official Zetrix brand asset before merge — just let me know the preferred source).
• src/utils/supportedChains/supportedChains.test.ts — test coverage for the new entry.

Details

• RPC: https://z2-test-node.zetrix.com
• Explorer: https://z2-test-explorer.zetrix.com (EIP-3091)
• chainId 938748 is registered in ethereum-lists/chains (PR Add Zetrix L2 Testnet (chainId 938748) ethereum-lists/chains#8523).

Tests

npx vitest --run src/utils/supportedChains/supportedChains.test.ts → 15 passed (incl. the new zetrixL2Testnet case).
