Hygiene: make JSDoc configs consistent

Make the Popups, MobileFrontend, and MinervaNeue JSDocs consistent. For
MinervaNeue:

- Replace "packageX" option which was unfound in the JSDoc repo with
  "package".

- Remove redundant default configurations.

- Replace tabs with spaces since that's the standard in this repo.
