Fix debug text color - add black color to text labels

- Added color: black to all div elements and the container
- Text labels were white on gray background (unreadable)
- Now shows: isAdmin=true, isFirstUser=true, form=EXISTS, useOnlyPlanHours=false, useGoogleSheetAsDefault=false
- Both useOnlyPlanHours and useGoogleSheetAsDefault are false, explaining why Plan hours tab doesn't show
- General tab should still be visible since it has no *ngIf conditions
