Update data usage UX
Update the UX and dig the data usage screen out of a huge whole of
technical debt. Switch every to use Preferences rather than standard
layouts and ListViews.
Split data usage into several fragments, all separated.
DataUsageSummary:
- Shows a summary of the 'default' usage at the top, this will be
the default sim on phones, or wifi if it has it, or ethernet
as last attempt to show something.
- Also has individual categories for each network type that has
data, cell, wifi, and ethernet. Maybe should look into bt though?
DataUsageList:
- Takes a NetworkTemplate as an input, and can only be reached from
the network specific categories in DataUsageSummary
- Shows a graph of current usage for that network and links to
app detail page for any app.
- Has gear link to quick get to billing cycle screen if available
BillingCycleSettings:
- Just a screen with the cycle day and warning/limits separated
out from the data usage.
AppDataUsage:
- App specific data usage details
- May need some UX iteration given lack of clarity in the spec
