Change label of Error Index page "Status" column

[amedina]

Feedback from the AMP team suggests that we should change the label of the status for validation errors from "Status" to "Sanitization Status" reflecting the fact that actions taken by the user refer to the sanitization actions of the plugin, and not the error themselves.

That string is a bit long for the column. Can we just do "Sanitization"?

[alcurrie]

Should this task be added to the 1.0.2 milestone?

[westonruter]

If @amedina confirms the shorter column label.

[amedina]

Confirmed. Let's go with 'Sanitization' as a replacement for 'Status'

[westonruter]

What would we do with the Status dropdown?

“All Sanitizations” no me cae bien.

Done in #3630.
