chore(e2e): prune reliability.perf.latency.under_slo coverage cell (#34024)

It is a non-binary latency SLO threshold rather than a deterministic pass/fail
behavior a single e2e test can assert, so it does not fit the coverage registry's
one-test-per-cell contract. The registry README already flagged the perf cells for
a support-check or prune, and throughput SLO under load is covered structurally by
the Locust load suite. Removing it keeps the denominator to behaviors an e2e test
can deterministically prove.
