Pull request overview

This PR makes user-facing exceptions in the data_grand_lyon integration translatable by switching raised exceptions to use translation_domain/translation_key and adding the corresponding exceptions translations.

Changes:

• Add translatable exception messages to strings.json for authentication failures and “all stops failed” update failures.
• Update the coordinator to raise ConfigEntryAuthFailed and UpdateFailed using translation keys instead of hard-coded English strings.
• Mark entity-translations and exception-translations as done in the integration quality scale file.
