White text on white background when renaming pool in dark mode

[philrz]

Repro is with Zui commit 639e339.

A community user recently reported in a Slack message:

when I try to rename a pool/query in dark mode the text and the textbox both appear white - is that a style thing or my desktop settings?

As shown in the video below, this is indeed a bug that we should fix.

Verified in Zui commit d372553.

As shown in the attached video, now the text for the pool name is visible while performing the rename.
