fix(grid): keep the award columns' position in the saved layout

Award columns were filtered out of the persisted column state entirely,
so applyColumnState({applyOrder:true}) had nowhere to put them and AG
Grid appended what the state does not mention. A column the operator
dragged to sit AFTER an award column therefore jumped back in front of
it on every reload.

Only the `hide` property is dropped now. Visibility stays owned by the
awardShown code-set — that is what stopped shown award columns from
vanishing on an awardCols rebuild — while the position survives the
round-trip.
