Why this matters

frontend/src/hooks/useIncomingStreams.ts is untested. Critical react-query behavior is unverified: incomingStreamsQueryKey, enabled-gating on publicKey, onSuccess invalidating the exact key, and the mutation throwing connect your wallet first when session is null.

Acceptance criteria

• Test useIncomingStreams stays disabled (no fetch) when publicKey is null/undefined
• Test the query key shape returned by incomingStreamsQueryKey
• Test useWithdrawIncomingStream rejects when session is null and invalidates incomingStreamsQueryKey(publicKey) on success
• Mock fetchIncomingStreams/withdrawFromStream with a QueryClientProvider wrapper

Files to touch

• frontend/src/hooks/useIncomingStreams.ts

Out of scope

• Tests for lib/api/_shared.ts
