refactor(ui): Sidebar 1:1 an enconf-Pattern angleichen

- <aside> → <nav> als Root-Element
- Section-Label-Div NEBEN dem <ul> (vorher verschachtelt)
- <NavLink>-Callback → <Link> + location.pathname-Vergleich (Pattern
  identisch zu netcell-webpanel/management-ui/src/components/Layout/Sidebar.tsx)
- nmg-prefix CSS-Variable `--nmg-sidebar-text` entfernt, Textfarbe
  direkt #94A3B8 (enconf-Standard)

Färbung war schon enconf-konform (Gradient #0B1426→#101D33→#0D1829,
Akzent-Stab #1677ff mit color-mix tint), nur Struktur+Markup zogen
nach.
