[fix](trx-frontend): serialize plugin loading

The runner image's `reuse` failed to import (NoEncodingModuleError): it
needs an encoding-detection backend, which the bare `reuse` install does
not provide and which libmagic/`file` is not present to satisfy. Install
`reuse[charset-normalizer]` so the reuse job can run in the image.

Rebuild the runner image and recreate the containers to pick this up.
