fix(tempo): include withdrawal fallback nonce

[struong]

Summary

Fixes the existing WithdrawalSenderTag.from API from #348 to derive nonce-bound Tempo Zone withdrawal sender tags.

Motivation

Zone user withdrawals hash sender || transactionHash || fallbackNonce. Omitting fallbackNonce returns a tag that cannot locate the parent-chain WithdrawalProcessed event.

The implementation follows the production Zone source at revision 689ffbe: Withdrawal::sender_tag defines the hash preimage, and WithdrawalRequested exposes fallbackNonce.

Changes

• Required fallbackNonce in the existing WithdrawalSenderTag.from input.
• Included the nonce as a packed uint64 for user withdrawals.
• Preserved the canonical zero-sender deposit bounce-back tag.
• Updated the existing runtime and type tests and added a patch changeset.

Testing

• pnpm test --project tempo-unit --bail=1 src/tempo/WithdrawalSenderTag.test.ts
• pnpm check:types
• pnpm check
• Verified the production vector returns 0xf1acbae45cd689281144042331e3379cf631a8d2db83057ccf38754a0b0108f2.

Superseded by #384 so Viem main can consume the fix from its Ox 0.x dependency line.
