fix(aci): Change open period range boundary to inclusive

[snigdhas]

Some issues have the same regression/resolution time in our db and the range boundary today would reject those as valid start/end times for open periods. Updating the boundary to be inclusive on both ends should fix this and allow an open period to start at the same time that the previous one ends.

Hm ADD CONSTRAINT EXCLUDE is an unsafe operation -- we can wipe the table and pause writes before applying this if that would make it safe? Otherwise the safer suggestion is to make a new table 🤔

[snigdhas]

Talked to @wedamija - we'll turn off the ff for writes and run the post-deploy migration to delete rows before running this migration with SafeRunSQL.
