Add status filter to app index and update status values displayed in table

[hstove]

Add a new filter to the top of the admin index screen for filtering all displayed apps by any of the following types of "Status":

• Pending Audit: Apps that have been submitted but not set to "Accepted" on their admin app pages
• Pending App Mining: Apps with "Blockstack" set for authentication type that have been set to "Accepted" on their admin app pages but haven't provided all data needed for App Mining enrollment
• Accepted: Apps with that have been set to "Accepted" on their admin app pages and either A) have "Blockstack" set for authentication type and have provided all data needed for App Mining enrollment or B) have any other authentication type
• Rejected: Apps set to "Rejected" on their admin app pages

Also, update the "Status" column in the apps table on this page to use the same status values as above. Currently, these values are simply broken in any case 😑

@jasperjansz I've updated this issue's specification to simply around just one new filter ("Status") instead of an additional "Authentication" filter. Can you review and update the correspondingly linked Figma design?
