* Admin UI update basics
Added the basics for the Admin UI/style update. Very far from being done...
* Admin style updates
- exploring menu
- enabling full width content (integrations selection bg)
- updated main screens

- `startDateLabel` was never populated after refactoring the members chart to use the members stats service
- use the first date that's returned as part of the members stats days array so that we can account for any potential time period being selected

no issue
- move members loading code into `members` controller so that it's more accessible to other areas of the app
- add `refreshData()` to the `members` controller which forces members list and stats to be re-fetched
- call `members.refreshData()` after successful upload of members import file
- store range/days in `membersStats` service so that it's remembered across refreshes and component renders
no issue
- "stale data" logic was incorrect so we were always returning `undefined` from `membersStats.fetch()`
- improved behaviour of the chart when stats are not available or are loading
no issue
- added a `member-stats` service to keep member stats state outside of the chart component's lifecycle
- returns memoized member stats when fetching if the query hasn't changed and the data is less than a minute old
- reduces potentially heavy network requests when quickly navigating between members list and other screens
no issue
- added mocked API for `/admin/members/stats/` that generates random data for the chart
- re-architected `<GhMembersChart>` to fetch data from the API rather than calculating stats from all members loaded in memory
- enabled mirage in development so that the chart can be tested before the live API is ready
no issue.
- improved the Y axis of members list chart to only take the visible range into consideration. This way the change in a period is more understandable
- added labels to Y axis so that the range is clearer
