The usage queue read drains the proxy. A batch that is then not written (the
client or the bus refuses its shape, an ambiguous key owner, a failed write) is
lost, and the Console showed proxy totals with no sign of it. The reader now
counts these per enabled business since the bus started, the proxy view returns
the count as droppedBatches, and the Console proxy section says so above 0.
A read that failed before the proxy answered or that it refused drained nothing
and is not counted. Telemetry only; no quota reads it. The log line stays
proxy-usage-read-failed.
