* fix(engine): preserve video frame replacement geometry
* test(producer): cover video overlay stretch regression
* fix(engine): always pass clip to Page.captureScreenshot
Without an explicit clip, Chrome can resolve replaced-element sizing
differently at dpr=1 when full-bleed absolute videos interact with
overlay layers — producing anisotropic frame stretching on some
compositor paths. Always passing clip with scale=dpr (including 1)
ensures geometry is locked to the measured viewport dimensions.

* test(producer): regenerate style-9-prod baseline for always-clip capture path
The always-clip change in screenshotService.ts routes Chrome through a
different compositor capture path at dpr=1, producing different video
frame compression artifacts. Regenerated inside Dockerfile.test to match
CI environment.
