TestStartSweeper_TransientErrorDoesNotCrashLoop leaks an in-flight
metric write across the test boundary: cycleDone fires inside the
fake's Sweep defer (before Sweep returns), waitForCycle returns
immediately after, cancel() lands, but the goroutine still has
metrics.PendingUploadsSweepError() to execute. Whether that write
happens before or after the next test's metricDelta() baseline read
is a coin-flip on slow CI hosts.

Outcome: TestStartSweeper_RecordsMetricsOnSuccess fails with
"error counter delta = 1, want 0" — looks like a real bug, isn't.
Instrumented analysis (per the file's existing waitForMetricDelta
docstring covering the same shape) confirms the metric IS getting
recorded, just AFTER the next test reads its baseline.

The Records* tests already use waitForMetricDelta to close this race
on their own assertions. This change extends the same shape to
TransientErrorDoesNotCrashLoop so it doesn't poison subsequent tests'
baselines.

Verified by running `go test -race -count=20 ./internal/pendinguploads/...`
locally — passes deterministically.
