Hard code a "close task" action on every column Trigger

Summary: Depends on D20287. Ref T5474. This hard-codes a storage value for every trigger, with a "Change status to <default closed status>" rule and two bogus rules. Rules may now apply transactions when cards are dropped.

Test Plan: Dragged cards to a column with a trigger, saw them close.
