Subject: [PATCH] WebxdcStoreActivity: log main-frame WebView load errors

The WebxdcStoreActivity loads a remote store URL via webView.loadUrl
(Prefs.getWebxdcStoreUrl). The current WebViewClient overrides
shouldOverrideUrlLoading and shouldInterceptRequest, but not
onReceivedError, so a failure at the WebView/network layer
(URL resolution, TLS handshake, premature reset) is silent: nothing in
adb logcat and no signal in the activity itself.

interceptRequest already catches RPC failures and synthesises a plain
text "Could not load apps. Are you online?" response, which covers the
common offline case. But it can only do so once shouldInterceptRequest
is actually invoked, which is not guaranteed for every kind of load
failure. The point of this change is to leave a trace in the log for
those leftover cases.

Add onReceivedError on the same anonymous WebViewClient (API 23+), guard
with request.isForMainFrame() so transient sub-resource errors do not
spam the log, and log the error code and description via the existing
Log helper and TAG.
