Description

Removes the custom Yarn patching of appwright (and related form-data override) and drops appwright from dependencies/unplugged resolutions.

Deletes the Appwright-based E2E/performance test harness (tests/appwright.config.ts plus the Appwright* helpers and performance fixture exports), leaving the repo without Appwright-specific test entrypoints.

Updates yarn.lock accordingly to prune appwright and a large set of transitive packages (notably ffmpeg/sharp/webdriver* related entries) and to simplify some version ranges/dedupes.
