chore: revert bignumber.js patch for charts and reapply the original bignumber.js change to SQL editor in an opt-in fashion (#7210)

* revert: bignumber patch to prevent rendering regression in charts

* Revert "Fix rendering regression from the introduction of bignumber (#6937)"

* fix: consume the bignumber.js reversion -- apply the bignumber conversion in `actions/sqlLab.js` where it is needed (aka opt into bignumber.js).

* Revert "Fix deck.gl form data (#6953)" b/c formData now returns snake_cased properties for deck vizzes.
