Feature/map 922 aggregation options for displays

[janbaykara]

Based on work with the Migrant Democracy Project's recent data ingests, this PR does a few things to the Area Explorer display queries and UI:

• Gives control over to the user to decide how to rollup/drilldown data. Just this area, stats in child areas, pull in parent area data? Etc. etc. This should fix MAP-926
• An explicit display option for displaying aggregated data, or breakdown data of individual records with a carousel.
• This PR also fixes the breadcrumb data issue; closes MAP-869

For now, query and display options are not saved. This is awaiting the refactor of config options in MAP-923.
