Validate language translations

Dry-run a translation write without persisting anything. The request body is the same body the update accepts, and the response on the failing paths is exactly the problem that update would return — the same key allowlist and the same placeholder checks run, only persistence is skipped. On a body that would apply, the response is a 200 `customiser_language_translations_validation` confirmation. Nothing is written, no caches are touched, no idempotency key is consumed, and no activity is recorded, so the operation is always safe to repeat. The verdict is advisory: nothing binds it to a later update, and the catalogue can legitimately change between the two calls. Requires the `customisers:write` scope, because it is the write dry-run twin. A 400 problem means the body is not valid JSON; 422 problems carry the update own `invalid_translation_key`, `validation_failed`, or `unknown_field` diagnostics. 401, 403, 404, and 429 problems behave as on the update operation.
