- Import and use internal/config.Load() in telesrv-admin instead of manual env parsing - Remove envOr() helper function (now consolidated in config package) - Add comprehensive .env.example documentation for Admin API/UI settings including: - TELESRV_ADMIN_API_TOKEN - TELESRV_ADMIN_UI_PASSWORD and TELESRV_ADMIN_UI_TOKEN - TELESRV_ADMIN_SESSION_KEY with security guidance - Optional address configuration parameters - Improve config validation error handling
