fix(stream): log main-frame WebView load errors via onReceivedError

[jim-daf]

Closes #1133.

The two stream-overlay WebViewClients in ui/main/stream/ (StreamWebView.kt and StreamView.kt) override shouldOverrideUrlLoading (plus onPageFinished on the Compose one) but neither overrides onReceivedError. When the embed fails to load (network drop, DNS, the player URL moves), the WebView just stays blank with nothing in the log to point at.

Add a main-frame-only onReceivedError override on both clients that logs the failing URL and description through the existing KotlinLogging.logger(...) used elsewhere in the codebase:

override fun onReceivedError(
    view: WebView?,
    request: WebResourceRequest?,
    error: WebResourceError?,
) {
    super.onReceivedError(view, request, error)
    if (request?.isForMainFrame != true) return
    val description = if (Build.VERSION.SDK_INT >= 23) {
        error?.description?.toString().orEmpty()
    } else {
        ""
    }
    logger.warn { "Stream WebView failed to load ${request.url}: $description" }
}

isForMainFrame gate keeps blocked sub-resources from spamming the log on every embed. No UX change: the overlay still does the same thing on success, but stream playback failures now leave a trace.

Makes sense to add some logging, just two nitpicks

Done. @flex3r I put the logging you requested. You can check if everything is okay and let me know

Seems like the linter is not happy with the import order. Running ./gradlew spotlessApply should fix it.

@flex3r i fixed the import order and also rebased so there are no conflicts with your develop branch

Thanks!
