Note

Adds centralized serviceKeys for API keys and updates Ethereum tools/adapters/fees to use them with deprecation fallbacks.

• Common:
  • Service Keys: Add ServiceKeys type and cleaner in src/common/types.ts and new helpers getRandomServiceKey/getServiceKeyIndex in src/common/serviceKeys.ts.
• Ethereum:
  • Init Options: Extend EthereumInitOptions with serviceKeys (and infuraProjectId), mark legacy keys (e.g., etherscanApiKey, evmScanApiKey, amberdataApiKey, etc.) as deprecated via asEthereumInitOptions.
  • Tools: Validate init options with asEthereumInitOptions in EthereumTools.
  • Fees: Update getEvmScanApiKey to prefer serviceKeys (by host via getServiceKeyIndex), fallback to deprecated keys with warnings.
  • Network Adapters: Migrate API key resolution to serviceKeys with fallbacks in AmberdataAdapter, BlockchairAdapter, BlockcypherAdapter, BlockbookWsAdapter, and RpcAdapter (including RPC URL template key replacement and error messaging).
• Tests:
  • Update feeProvider.test.ts to supply serviceKeys for EvmScan test.

Bug: Type check uses value comparison instead of typeof

The addRpcApiKey function's fallback for deprecated API keys incorrectly checks cleanApiKey === 'string' instead of typeof cleanApiKey === 'string'. This prevents the fallback from working, leading to "Missing serviceKeys" errors for users relying on deprecated initOptions like infuraProjectId.
