Fix errors when hovering action column header (#16484)

### What does it do?
ExtJS is grabbing the header by regex on class `'x-grid3-td-([^\\s]+)'`,
for some reason the class for action column header doesn't populate
correctly (when using column model). Manually specifying an id fixes the
issue.

### Why is it needed?
Get rid of the errors

### How to test
Open system settings & console. hover over the action column header.
