What does this PR do?

Let Jetty BadMessageException with status HttpStatus.PAYLOAD_TOO_LARGE_413 propagate back to the existing unified OversizedRequestErrorHandler instead of being absorbed inside the servlet/filter chain.

The change has two parts:

• RateLimiterServlet no longer handles oversized-request BadMessageException locally; it rethrows it.
• HttpInterceptor still records failure metrics, but now rethrows only BadMessageException(413) so that oversized chunked requests can reach Jetty's existing unified error path. Other exceptions keep the previous swallow-and-meter behavior.

This keeps chunked JSON-RPC oversized requests aligned with the pre-existing unified oversized-request handling path in HttpService, instead of introducing a servlet-specific 413 implementation.

Why are these changes required?

For Transfer-Encoding: chunked, Jetty only discovers an oversized request while the servlet is reading the request body. In the JSON-RPC path, that expected 413 exception used to be swallowed inside the servlet/filter chain before it could reach Jetty's unified oversized-request error handler, which led to noisy ERROR stack traces and inconsistent handling.

Other HTTP endpoints can hit the same Jetty streaming exception timing. Many HTTP servlets already catch and convert errors locally, but for paths where a 413 does bubble up, this change makes them reuse the same top-level oversized-request handler instead of splitting behavior between ad hoc local handling and Jetty error handling.

None.

Extra details

• RateLimiterServletTest now verifies that oversized-request BadMessageException is propagated rather than handled in-place.
• HttpInterceptorTest locks down the narrower behavior change: rethrow BadMessageException(413), keep swallowing non-413 exceptions.
• JsonrpcServiceTest still verifies that oversized chunked JSON-RPC requests return 413 end-to-end.
