feat: Sidebar Neumorphismus-Redesign + responsives Kollabieren

- 1024–1279px: Icon-only Sidebar (64px), Logo als Akzent-Icon
- ≥ 1280px: Sidebar mit Labels (200px), Logo Gradient-Text
- Neumorphischer Hintergrund (--sidebar-bg), eigene Light/Dark-Schatten-Tokens
- Hover: raised box-shadow (konvex gehoben)
- Aktiv: inset box-shadow (konkav gedrückt) + Akzentstreifen links
- Sidebar-Schatten statt Border-right für Tiefentrennung
- Smooth transition bei Breakpoint-Wechsel
