fix: use BUILDPLATFORM for native cross-compilation, remove broken cache mounts

Build and frontend stages now use --platform=$BUILDPLATFORM so Maven and
Node run natively on the ARM64 CI runner instead of under QEMU emulation.
Only the final JRE runtime stage targets amd64. Removed --mount=type=cache
which doesn't persist across CI runs with buildx --push; the registry layer
cache (--cache-from/--cache-to in CI) handles caching the dependency layer.
