Add JSON response format to entropy endpoints (#2673)

* Add JSON response format to entropy endpoints

Add account settings JSON endpoint returning account info including auto_postpone_period. Add auto_postpone_period to board JSON responses. Add JSON update support to both account and board entropy controllers.

* Add auto_postpone_period to all board response examples in API docs

* Use auto_postpone_period_in_days in JSON responses and API docs

* Use valid period values in permission tests
