build(frontend): enable multi-architecture yarn builds

Convert Dockerfile to use hermetic build approach with cachi2 and add
support for multiple architectures (x64, arm64, s390x, ppc64) in yarn
configuration. This resolves hermetic build failures on non-x86_64
architectures by ensuring all required architecture-specific packages
are included in dependency resolution.

The change simplifies the build process by removing complex corepack
setup and cachito integration in favor of the standard hermetic build
pattern used across OpenShift components.
