chore: Button cruft cleanup (#11342)

* toggleSchedule

* cleaning up run query button

* removing unnecessary (subtle!) style overrides

* bulk action classname to button style prop

* nixing btn-primary

* nixing cancelQuery class

* togglesave

* nixing autocomplete class

* linting

* nixing button classes of 'ok' and 'reset'

* unoing diagnostic test

* begrudgingly adding an m-r-3 class... for now

* this is not a class to worry about

* test fixes for limit control

* updating TODO notes, calling it a day for now.

* gah... copy paste error.
