Addresses user feedback on Phase 1:
- Dashboard reoriented from static stack facts to LIVE operational status.
New health banner surfaces faults prominently (green when all online;
amber/red with a pluralized problem count when a service is down).
Service tiles probe DB, Redis, Reverb (socket) and Horizon in real time
with latency; versions moved to a small, de-emphasized "System" block.
wire:poll.10s + a refresh button keep it live. Verified: stopping Reverb
flips the banner to "Ein Dienst mit Störung" and the Echtzeit tile to
Offline/nicht erreichbar (screenshotted), healthy state restores clean.
- Sidebar decluttered: removed the wrapping "In Kürze" count badges;
coming-soon items are now dimmed (still show lock icons where gated).
R12 re-verified in headless Chromium: 15/15 assertions, 0 console errors,
0 failed requests, breakpoints 375/768/1280. 7 feature tests still green.
