Oliver Kieselbach bc1f11d2db revert(backend): undo L4 telemetry sampling — ineffective in isolated worker
Deploy-verified on f4d51ea4: the worker-side adaptive-sampling exclusion
(EnableAdaptiveSampling=false + manual Configure<TelemetryConfiguration>
UseAdaptiveSampling(excludedTypes:"Request;Event")) does NOT take effect in the
Functions isolated worker. Live data showed the enriched worker request copy
(Source=WorkerMiddleware) sampled to ~63% while the redundant host request item
(Source="") stayed fully billed — strictly worse (lossy enriched copy, host
duplicate unchanged). host.json "Host.Results": "Error" likewise did not drop
the host request item (emitted by the host process, not governed by that level).

Restores known-good: default worker sampling (enriched copy complete at normal
traffic, burst-capped) + host.json Host.Results back to Information. L1 storage
dependency filter and L2 Function-trace suppression are unaffected and still
verified live. L4 deferred pending a mechanism verified against the isolated-
worker pipeline. H2/H3/O1/O2 from f4d51ea4 verified healthy (0 exceptions).
