fix: allow prepareTransactionRequest with calls and no top-level to

[deodad]

Problem

prepareTransactionRequest (both the core action and the query options used by usePrepareTransactionRequest) requires a top-level to parameter. The query options hardcode:

enabled: Boolean(options.to && (options.query?.enabled ?? true))
// ...
if (!parameters.to) throw new Error('to is required')

This makes it impossible to use with batched calls (e.g. EIP-5792 sendCalls flows) where each call carries its own to address and no top-level to is needed. Viem's underlying prepareTransactionRequest does not have this restriction.

Fix

• Make to optional in the action's type definition
• Update enabled guard to accept calls as an alternative to to
• Update queryFn guard to allow calls without to
• Add test for calls-only usage
