Subject: [PATCH] fix: dev-console capture uses Blob with JSON content-type and
 fetch fallback

sendBeacon with a plain string sends Content-Type text/plain, which can
be silently blocked in Telegram WebView. Use a Blob with application/json
instead, and fall back to fetch with keepalive when sendBeacon is
unavailable or returns false.
