feat: statics configuration for zksyncera

[ArunBala-Bitgo]

Ticket: WIN-8193

Summary

Adds statics configuration for zkSync Era blockchain, enabling support for the zkSync Era network in BitGo.

Changes

Statics Configuration

Networks (modules/statics/src/networks.ts):

1. Added ZkSyncEra mainnet class (chainId: 324)
2. Added ZkSyncEraTestnet class (chainId: 300, Sepolia)
3. Configured explorer URLs, contract addresses, and operation hash prefixes

Coin Definition (modules/statics/src/allCoinsAndTokens.ts):

1. Added zksyncera (mainnet) and tzksyncera (testnet) coins
2. Uses ZKSYNCERA_FEATURES feature set

Base Types (modules/statics/src/base.ts):

1. Added CoinFamily.ZKSYNCERA
2. Added UnderlyingAsset.ZKSYNCERA

Coin Features (modules/statics/src/coinFeatures.ts):

1. Added ZKSYNCERA_FEATURES with shared EVM SDK support, multisig cold, and rollup chain features

Environment Configuration

Environments (modules/sdk-core/src/bitgo/environments.ts):

1. Added zksyncera to evm config for mainnet and testnet

Test Updates

1. Updated expectedColdFeatures.ts to include zksyncera/tzksyncera in the "both" category (supports both multisig and TSS cold)
2. Added exclusion for UnderlyingAsset.ZKSYNCERA in keychains test (pending coin-specific module)
3. Added unit tests for zkSync Era configuration

Notes

1. zkSync Era shares chainId 324/300 with existing zketh coin
2. coinNameFromChainId(324) returns 'zketh' for backward compatibility
3. zksyncera is accessible via coins.get('zksyncera') directly
