fix(futures): enforce result deadline where no cancel scope arms
cancel_sync_after returns a NullCancelScope on win32, so a slow result retrieval could overrun the caller's timeout without any cancellation being delivered. Check the deadline after each retrieval so the timeout is enforced on every platform.

fix(futures): convert cancellation during result retrieval to TimeoutError
A cancel scope delivers cancellation into the frame the supervised thread is currently in. While as_completed is suspended at its yield that frame is result(), so timeout_context never sees the CancelledError and cannot convert it, letting a BaseException escape past a caller's except Exception. Claim it in result() when our own deadline has passed, leaving cancellation from enclosing scopes (e.g. a flow run timeout) untouched.

fix(futures): drop redundant timeout scope in PrefectFutureList.result
result() wrapped the loop in its own timeout scope while also passing the timeout to as_completed, arming two enforcers for the same deadline. In worker threads both fire at once and the losing enforcer can inject a stray CancelledError after the scope exits, wedging later work. as_completed's scope stays entered across the loop body, so it already bounds result retrieval.

test: drop timeout-scoped passthrough test that destabilizes CI workers
The 5s wait scope can fire under CI load and inject a CancelledError into the xdist worker thread; the existing passthrough test plus the type-based guard already cover this.
