PR Summary

Low Risk
Low risk documentation-only changes, primarily adding new markdown pages and updating navigation cards; main risk is broken links/formatting across locales.

Overview
Adds a new server-truenas-scale documentation guide covering installation and initial configuration of TrueNAS SCALE on dedicated servers, plus full translated versions across multiple locales.

Updates software-overview-services.md (and its localized variants) to surface the new guide via an added Windows software card, along with a few minor wording/consistency edits in some translations.
