Vendored assets

These files are copied from server/build/ in the Mattermost monorepo so that @mattermost/playwright-lib's Testcontainers support is self-contained once published to npm (it can't reach outside its own package at runtime). If the source files change, these copies need to be refreshed manually — they are not symlinked or build-generated.
