Align remaining denoHttpIntegration options with httpIntegration #23481

Follow-up to #23313 (aligned most of denoHttpIntegration's option names with httpIntegration). Remaining todos:

• Outgoing request hooks missing in Deno. outgoingRequestHook and outgoingResponseHook already match core's names, so declaring them is enough now that options are spread through.
  • Open question: only applyCustomAttributesOnSpan diverges. Use core's name, or match Node's outgoingRequestApplyCustomAttributes (needs explicit mapping, like tracePropagation→propagateTrace)?
• ignoreStatusCodes is a no-op in Deno. declared on HttpInstrumentationOptions but only implemented in Node's httpServerSpansIntegration.processEvent.
  • Fix: move shouldFilterStatusCode into @sentry/core for both to share, or give Deno its own processEvent. Either way, don't leave it declared-but-unread on the shared contract.
• onSpanEnd asymmetry. Deno has it, Node doesn't, though core's server subscription supports it. Better to add it to httpIntegration than remove it from Deno.
  • Worth noting this is a new capability, not a regression from ref(node)!: Remove legacy incoming HTTP span hooks and default keepAlive to true #23396. Node's incoming hooks all fire at span creation, so it never had an end-time hook for incoming spans (v10's responseHook was a misnomer there). Deno's fires on response close, after the status attributes are set.
