/diseases/charts/regions
Returns distinct region options that appear in the GIDEON chart catalog, for building chart filters or autocompletes. Pair with GET /diseases/charts/countries for country pickers scoped the same way.
Each item has id (numeric id for chart filters), source (countryregion or state), and name (label). Use source to decide how to pass the id into GET /diseases/charts: state rows correspond to the states query parameter; countryregion rows correspond to countryregions.
All query parameters are optional; omitting filters returns a larger set (still limited to regions that appear on charts in the catalog).
