A maintenance release with device selector polish and sharing-screen fixes.

Device Management

• Devices that can't run your event are now disabled in the device list, with an "Update required" badge linking to update instructions.
• Apple and Windows platform icons are shown next to each LumaBooth subscription so it's immediately clear which platform it covers.

Sharing & Uploads

• Start screen videos uploaded from the dashboard now play correctly on the booth.
• Fixed a confusing error message when uploading overlay images with the wrong dimensions.

Update Alerts

• When an app update is required, the update popup now includes a link to the latest release notes so you can see what's new before updating.
