feat: add wallet_connect RPC method for Base Account authentication

[simaonogueira101]

Description

Adds support for the new wallet_connect RPC method (ERC-7846) for Base Account connections in the Ethers and Ethers5 adapters.

Why wallet_connect over eth_requestAccounts?

While eth_requestAccounts (EIP-1102) still works, wallet_connect is the modern, recommended approach that offers:

• Combined connection + authentication - Reduces user prompts from 2 to 1
• Built-in SIWE support - Sign-In With Ethereum (ERC-4361) integration
• Better UX - Streamlined single-step connection flow
• Extensibility - Supports additional capabilities via ERC-5792

"By unifying connection and authentication into one step, apps can reduce friction, improve the user experience, and minimize redundant interactions." — ERC-7846

Changes

• Added wallet_connect RPC method handling for Base Account connections in EthersAdapter
• Added wallet_connect RPC method handling for Base Account connections in Ethers5Adapter
• Updated error message to reflect "Base Account SDK" branding
• Bumped @base-org/account to v2.5.0

Type of change

• New feature (non-breaking change which adds functionality)

Associated Issues

Closes #5382
