Remove dead EthereumContract base class, getDefaultConfig helper, and clean up types

[Copilot]

EthereumContractConfigInternal, the EthereumContract base class, and getDefaultEthereumClientConfig were left unreferenced after the refactor to pass ethPublicClient directly into each contract client's config. Also fixes PublicClient being imported as a value instead of a type in types.ts.

Changes

• Deleted EthereumContract.ts — abstract base class with no subclasses; superseded by the per-contract ethPublicClient config pattern
• Deleted getDefaultConfig.ts — getDefaultEthereumClientConfig was never called anywhere after the refactor
• types.ts — removed EthereumContractConfigInternal (only referenced by the now-deleted files) and its unused viem import
