🚀 Add Nostr profile job, Hungarian translations, and Horizon integration

- Introduced `FetchNostrProfileJob` for retrieving and updating user Nostr profiles.
- Added Hungarian translations (`auth.php`, `passwords.php`, `validation.php`, and others) for improved localization.
- Integrated Laravel Horizon for enhanced queue management (`HorizonServiceProvider` added, `composer.json` updated).
- Updated German and Spanish language files to fix duplicate keys.
- Minor route addition for testing Nostr profile job dispatch.
