fix(widgets): drop redundant self.* assignments (CodeQL overwritten-inherited-attribute)

FormatCustomText.__init__ and JobStatusBar.__init__ set instance
attributes (format; name/left/right/fill) that their super().__init__
immediately re-sets from the same values, which CodeQL flags as
overwriting the inherited attribute. Remove the duplicates; the base
initializers (FormatWidgetMixin, Bar, VariableMixin) set them. Verified
attrs identical after construction; no behavior change.
