add REUSE.toml attributions for new base.ts translation files

Each language's base.ts was derived from an upstream npm package
(now removed). Add proper SPDX annotations crediting the original
package authors (MIT) alongside etke.cc (Apache-2.0), using the
combined Apache-2.0 AND MIT identifier for MIT-sourced files and
plain Apache-2.0 for the German file (originally Apache-2.0).
