Brings every template up to Studio SDK 2.30.1, a fixes-only release.

• Clips with a filter look in the preview the way the cloud render applies them (fix: draw clip filters in the preview as the render applies them shotstack-studio-sdk#265).
• html5 clips keep their embedded images in Safari and their gradients in Firefox ([1/2] fix: keep a frame's embedded images when Safari draws an html5 clip shotstack-studio-sdk#279, [2/2] fix: draw html5 frames on a software canvas so Firefox keeps their gradients shotstack-studio-sdk#280), and keep preparing while their tab is in the background (fix: keep baking html5 clips while their tab is in the background shotstack-studio-sdk#281).
• Apps that export video in the browser get white whites from Safari (fix(export): tag browser exports as limited range so Safari's whites stay white shotstack-studio-sdk#277) and real frames instead of black ones from Firefox (fix(export): draw export frames into one stencil target so Firefox keeps masked content shotstack-studio-sdk#278).

Each lockfile is written with npm 11, so the libc fields stay. The only change in each lockfile is the SDK entry. New scaffolds get this once create-video-editor is next released.

Verify: npm install && npm run build in each of templates/{angular,nextjs,react,typescript,vue}, plus npm run lint in react. All pass locally on Node 22, same as master.
