* Export Formatting Correctness

WIP

Several bugs exist around the correctness of export formatting, this aims to fix them.

Fixes #27374

When a model has viz settings/metadata changed after save, the download won't incorporate said changes. At least it's
clear that scale doesn't work.

* number formatter merges settings from columns too

* column formatting on aggregated cols works in xlsx now too

* fixes 43040 by grabbing global-type-settings in csv formatter
