🛠️ Fix: Screencast Blank Screen on Mobile Devices (Issue #1043)

🔍 Problem Summary

When users attempted to use the screencast feature on mobile devices with a video that has a recorder form layer, the shared screen appeared blank. This made it impossible to see the screen content during screencast sessions on both Android and iOS devices.

Steps to reproduce:

1. Add any video to a page that has a form layer with a recorder.
2. Open the page on a mobile device.
3. Start screen sharing (screencast).
4. Observe that the shared screen is blank instead of showing actual content.

✅ What This PR Fixes

#1043

[Copilot]

Pull request overview

This PR fixes a blank screen issue during screencast sessions on mobile devices by adding browser/OS capability detection for screen capture support. The fix prevents the ScreenCapture plugin from being initialized when the underlying getDisplayMedia API is not available.

Changes:

• Added feature detection check before enabling ScreenCapture plugin
• Implemented isScreenCaptureAvailable() method to verify browser support for screen capture API
