Homescreen Improvements

Container issue, should be split out

1. Persisted Per User Settings. Should be a framework to support things like
   • Track if user has logged in before
   • Track if user has dismissed 'new user' setting
2. Rearrange homescreen content
   • Remove recent activity from homescreen, use standard drop down shown on other pages
   • Move favourites over to where recent activity is
3. Show 'Welcome to stratos' style content where favourites used to be
   • user can 'dismiss' this message
4. Show Endpoint Status cards where favourites used to be
   • Each endpoint type has card that shows basic stats for that type
   • Card component and supporting services should not be lazy loaded
   • Should consider the case where only one endpoint type is registered (or not hidden aka sandbox... or user has hidden?)
5. Allow an admin to hide specific endpoints from non-admins
   • Should be specified at registration time?
   • Should be a backend thing, non-users should not see them? Would they still need to access the info like metrics?
6. Allow an admin to hide the endpoints tab from non-admins

No files, tests, or entry points are named. First split the container issue into focused frontend, backend, and authorization tasks, then identify the homescreen and endpoint-registration entry points; done means the resulting tasks have settled scope and acceptance criteria for each listed behavior.
