Two UI fixes:
1. MessageBubble: 'Nachricht nicht lesbar' was rendered with
text-fg-muted on the blue 'mine' bubble — invisible. Now uses
text-accent-fg/80 on mine, text-fg-muted on peer (still
≥4.5:1 contrast in both modes).
2. SettingsPage: redesigned from a long single-column scroll into a
sticky-sidebar + content layout (lg+) with:
- 9 anchor-linked sections with icons in the sidebar
- IntersectionObserver highlights the active section
- Each section has a description subtitle for context
- Voice (the densest section) is now sub-grouped into Audio-Gerät /
Qualität / PTT / Hotkeys / E2EE via SubSection cards
- Notifications consolidates message-sound + ringtone
- Danger-toned account section visually separated
- Mobile fallback is the original single-column scroll
