1. Improve Preferred-Language Fallback after the Current Accept-Language Rollout

The current auth-registration flow derives the preferred-language candidate from the public Accept-Language header and falls back to en when no supported tag is available.

A later improvement may use the existing geoip package as an additional fallback when Accept-Language is absent or unusable, but it must:

• preserve the current public JSON DTOs
• continue emitting a valid BCP 47 tag for User Service
• keep en as the final safe fallback
