Labels: frontend, testing, Stellar Wave

frontend/src/hooks/useIncomingStreams.ts has no tests, and it holds a fair amount of react-query behavior that we're currently trusting blind.

The bits worth pinning down: incomingStreamsQueryKey, the enabled gating on publicKey, onSuccess invalidating exactly that key, and the mutation throwing "connect your wallet first" when the session is null.

Done when

• Test that the query stays disabled (no fetch) when publicKey is null/undefined
• Test the key shape returned by incomingStreamsQueryKey
• Test that useWithdrawIncomingStream rejects when session is null, and invalidates incomingStreamsQueryKey(publicKey) on success
• fetchIncomingStreams/withdrawFromStream mocked, with a QueryClientProvider wrapper
• lint + typecheck + tests green

Where to start
Test file next to useIncomingStreams.ts. Tests for lib/api/_shared.ts are out of scope. Small, self-contained.
