Fixes #8961

Description

• JdkHttpSender.send() forwarded the whenComplete throwable as-is, so onError received CompletionException(UncheckedIOException(IOException)). HttpExporter then recorded error.type=java.util.concurrent.CompletionException and used the wrapper as the logged exception and the FailedExportException cause.
• A private unwrap helper now strips one CompletionException layer, then one UncheckedIOException layer. Other exceptions pass through unchanged.
• For transport failures (connection refused, timeouts, TLS errors) onError now gets the same IOException as with OkHttpHttpSender. The RejectedExecutionException path in send() already did this.
• Out of scope: for body-too-large and unsupported-encoding failures, error.type is now the private IOException subclass name; OkHttp reports java.io.IOException.

Testing done

• JdkHttpSenderTest#send_ioException_callsOnError now asserts onError receives the thrown IOException (isSameAs) instead of checking the root cause. With the fix reverted it fails with CompletionException: java.io.UncheckedIOException: java.io.IOException: send failed.
• :exporters:sender:jdk:check: spotless, ErrorProne/NullAway and jApiCmp pass; 13 of 14 tests pass. sendInternal_RetryableConnectTimeoutException also fails on unmodified main here: it needs 10.255.255.1 to time out, and my VPN routes it.
• :exporters:otlp:all:testJdkHttpSender: 143 tests pass.
