Merge upstream quattro for the Qt 6.12 palette fix (#14553)

Qt 6.12 shadows the bare Color singleton, so the bar and every Color
role read undefined on fresh installs. Keep our I18n text in the four
conflicting files, qualify #14433's notification button color, give the
new dictation menu rows and notifications Chinese, and drop table
entries for the removed Voxtype and FIDO2 texts.
