Adds the same `statusPages` entry the web app uses, so the desktop app
shows the status banner for matrix.lotusguild.org too (Kuma status page
https://isitup.lotusguild.org/status/matrix). The desktop CSP already
allows https: connections; no other change is needed. Inert until the
bundled cinny includes the banner (cinny PR #255).
Tested on a Linux release build: with a local fake Kuma reporting calls
down, the desktop app shows "Voice calls are down right now. Messages
still work." and polls both endpoints; from inside the desktop app the
real Kuma page answers 200 on both (CSP and CORS allow it).
