* upstep bun and sqlite versions

* allow specific columns to be updated in the db

* only update necessary columns for user

* bit tidier

* only update necessary fields of media_attachment

* only update relevant instance fields

* update tests

* update only specific account columns

* use bool pointers on gtsmodels
includes attachment, status, account, user

* update columns more selectively

* test all default fields on new account insert

* updating remaining bools on gtsmodels
