fix(service): return 500 instead of crashing on translation error (#224)

Browse Source 
The /translate, /v1/translate and /v2/translate handlers called log.Fatalf when TranslateByDeepLX returned an error. log.Fatalf calls os.Exit, so a single failed translation would tear down the whole server process. Return a 500 JSON response and keep serving instead.
