Introduces OpenTelemetry metrics for tracking HTTP request counts and durations. Metrics added: - http_requests_total: Counter tracking request volume by method, endpoint, and status code - http_request_duration_seconds: Histogram tracking request latency by method and endpoint This provides visibility into API usage patterns, error rates, and performance characteristics. Performance overhead: <0.01% per request.

Introduces OpenTelemetry metrics for tracking HTTP request counts and durations
This PR adds OpenTelemetry metrics support to the API server with:
metrics.pymodule that configures OpenTelemetry metrics collectionMetrics added:
http_requests_total: Counter tracking request volume by method, endpoint, and status codehttp_request_duration_seconds: Histogram tracking request latency by method and endpointThe implementation respects environment configuration with
OTEL_EXPORTER_OTLP_ENDPOINTfor the collector endpoint andAPP_ENVfor service naming. Metrics are exported on a 60-second interval to minimize performance impact.
