Description

Switch wallet to viem with fallback rpcs from chainlist use @goodwidget/core createviemfallbackclient

Summary by Sourcery

Migrate blockchain wallet operations from Web3 to viem with cached fallback RPC clients while preserving transaction, contract, and KMS workflows.

New Features:

• Add viem-based wallet clients with GoodWidget fallback RPC discovery and chain configuration.
• Support viem-based contract reads, event queries, transaction encoding, and local or KMS transaction submission across wallet workflows.

Bug Fixes:

• Improve transaction recovery and receipt handling for nonce errors, insufficient funds, timeouts, and reverted transactions.

Enhancements:

• Replace Web3 wallet and contract interactions with viem clients while preserving wallet queues, callbacks, balances, fees, and KMS signing behavior.
• Update staking, fishing, verification, and wallet integrations for viem contract addresses, bigint values, event arguments, and account management.

Build:

• Add viem and @goodwidget/core dependencies and update the lockfile.

Tests:

• Update blockchain tests for viem APIs and add coverage for fallback RPC setup, transaction submission, KMS signing, nonce recovery, receipts, and bigint handling.

Chores:

• Adjust lint configuration and related formatting for the new wallet implementation.
