OcrClient is the third telemetry path that skips the chat onion: _emit
builds its own ChatRequest purely to reuse the shared TelemetryEmitter,
so wiring chat() and embed() alone left every OCR row without a tenant
while those rows land in the same llm_calls table. Take the dimensions
at both public entries, validate them there (anything failing further
down is degraded to a warning), and thread them through _call ->
_attempt -> _emit so success, rejection, cancellation and retryable
failure rows all carry the same pair.
