v0.1.46

Adding a self-signed server now asks about its certificate only once, and the Overview shows dashes instead of zeros when it has no data. The 0.1.46 beta confirmed this on a real phone: the trust question appears once, the Overview shows dashes while offline, Uptime is a duration and disk rows have no dangling separator.

Fixed

• The Overview shows a dash instead of zeros when it has no data — after the
  connection to your server dropped, the Array card read "0,0 / 0 TB used" with a
  half-filled bar, and CPU and Memory read "0,0%" and "0,0 GB". Values the app does
  not know now show a dash with an empty bar, like the Network and Temperature
  cards, and the graphs no longer draw zeros for them. A value your server really
  reports as zero is still shown as zero. For a few seconds after the connection
  drops the last values stay on screen on purpose: the app waits for a few failed
  polls before it calls the server offline (#303).
• Uptime on the Overview shows how long the server has been running — the
  System card showed a raw timestamp such as "2026-11-12T13:56:22.425Z", which is
  when the server started. It now shows the time since then, for example
  "22h 4m" or "3d 4h", and a dash when the server sends nothing readable (#304).
• Disk rows on the Array tab no longer end in a lonely "·" — a row showed
  "sdb ·" when the server sends no model for the disk. The second line now
  lists only what is known ("sdb") and is left out when nothing is (#305).
• A new self-signed server asks you to trust its certificate only once —
  when you added a server with "Trust self-signed certificate", confirmed the
  certificate during Test and then saved, the same "Trust this certificate?"
  dialog appeared a second time on the main screen. The certificate you accept
  is now stored together with the server, so it is already trusted when the
  server first connects. A certificate that later changes still asks (#292).
