* feat(otlp): persist metric exemplars

OTLP metric conversion now emits exemplars through the shared storage contract. It validates timestamps, IDs, values and label budgets, and associates histogram exemplars only with emitted buckets that contain their values. Invalid observations are dropped and counted while valid points and siblings remain ingestible.

Frontend ingestion authorizes the emitted destinations and retains confirmed completions across metric and exemplar writes, including logical-table batching. Includes conversion and schema-failure isolation tests; tests that also query the new Prometheus endpoint land in the final layer.
