[BUG] map query bugs and feature request

[patricialarsen]

Some portal issues we need to fix on the maps before release:

missing resolution nside 2048 in the query list
preview showing odd broken 10^18 numbers

then a feature request:
I'd like to be able to sum together the redshift slices to get a wider redshift range

Adding to this

• reporting units, especially on maps where unit conversions aren't supported would be great
• ra/dec column natively supported on lightcone objects would be great
