Atomic multi-operation batching with one passkey approval

[Miracle656]

Background

Today each action is a separate tx + passkey prompt. Composing several operations (approve + swap, or multi-send) into one signed transaction improves UX and atomicity.

What to build

A batch() API that collects multiple Soroban invocations into a single transaction, builds one auth payload, and gathers a single passkey assertion covering all auth contexts.

Key files

• sdk/src/useInvisibleWallet.ts
• contracts/invisible_wallet/src/lib.rs (verify multi-context __check_auth)

Acceptance criteria

• Multiple ops succeed/fail atomically
• One passkey assertion authorizes all contexts
• Test: partial-failure rolls back the whole batch
