feat: keep device information up to date

Previously, we only fetched the device information (including the
compliance state) once when loading the accounts. However the compliance
state can change over time (it is updated approximately every 1 hour).
To always show an up-to-date version, we refresh it if it is older than
30 mins. To avoid frequent API calls to MS, we perform the refresh lazily
when opening the UI.
