feat(recipes): add location open and recipe ID copy to recipe modal

Add a de-emphasized meta footer to the recipe modal, mirroring the model
modal's hash footnote: a clickable file location on the left (opens the
recipe JSON via the generic open-file-location route, with the Docker
clipboard fallback) and a middle-truncated recipe ID with copy button on
the right.

The recipe detail API now exposes recipe_json_path so the frontend does
not have to guess the on-disk storage layout. Translations for the new
recipes.modal.* keys are filled in for all 9 locales, reusing the model
modal's openFileLocation wording per locale.
