feat(network-details): Extract network details data to Session Replay

[43jay]

📜 Description

Upload network details data (SentryNetworkRequestData) extracted by SentryNetworkTracker to the session replay backend.

SentryNetworkRequestData
Stored on the NSURLSessionTask while waiting for data (see previous prs)

SentryNetworkRequestData *networkRequestData
        = objc_setAssociatedObject(sessionTask, &SentryNetworkRequestDataKey);

Stored in the Breadcrumb data after task has completed (addBreadcrumbForSessionTask) (THIS PR)

breadcrumbData[SentryReplayNetworkDetailsKey]

Extracted from Breadcrumb into RRWebEvent (SentrySRDefaultBreadcrumbConverter) (THIS PR)

 SentryNetworkRequestData.serialize

💡 Motivation and Context

Last leg of data upload; now data is visible in replay dash.

💚 How did you test it?

Manual Testing with iOS-Swift test app

1. Build and install

xcodebuild -workspace Sentry.xcworkspace -scheme iOS-Swift -sdk iphonesimulator -destination  'platform=iOS Simulator,name=iPhone 16 Pro' clean build

xcrun simctl install "iPhone 16 Pro"  ~/Library/Developer/Xcode/DerivedData/Sentry-*/Build/Products/Debug-iphonesimulator/iOS-Swift.app

2. Navigate to Extras > Network Details

3. Initiate different types of request

4. Navigate to sentry.io test project and confirm session replay 'Network' tab shows requests with correct body and headers.

https://sentry-sdks.sentry.io/explore/replays/f5cff413ffd94561819...

• Request + Response Headers correctly extracted

options.sessionReplay.networkRequestHeaders = [
                "User-Agent",
                "X-Custom-Header",
                "X-Request-ID"
            ]
            options.sessionReplay.networkResponseHeaders = [
                "Server",
                "Access-Control-Allow-Origin",
                "access-control-allow-credentials"
            ]

• Formurlencoded request/response bodies correctly extracted as structured data

• Binary content correct not extracted / extracted as placeholder

• JSON Body over 150KB limit correctly truncated and 'fixed up' (server-side) with expected warning in UI
