KIP-24: Times per period update, Curation court

I propose to change the times per period parameters for the Curation court to the following:

timesPerPeriod: [140400,291600,291600,194400]

Motivation: These are half of their current respective values, and with the proposed values would correspond to the period times of the Onboarding court. These values better reflect the amounts of time required to submit evidence to, rule on, and appeal disputes of the scale of those in the Curation court.
