Engineering technical report: gghstats ecosystem v1.6.0

Highlights

Responsive dashboard UX (#46): collapsible sidebar rail, light/dark/midnight theme cycle, language control with autonyms, mobile offcanvas polish (close-button fix, #56).
Gated Settings: GET /settings for allow-listed presentation preferences; API-token gate (or loopback-only without a token); browser path via Sync-style modal → short-lived HttpOnly HMAC session — usable on the selfhosted Traefik / 0.0.0.0 path.
Locales: Bulgarian (bg) and Russian (ru, experimental) enabled by default; existing locales updated for Settings/UI strings.
Optional soft skin: contrib/themes/example-soft-dashboard.css via GGHSTATS_CUSTOM_CSS (neo-brutalist app.css remains the default).
Compact numbers live: charts/formatting read the live SettingsManager snapshot after save (no restart).
