Fix overlapping feedback type selector with long labels

Replace the SingleChoiceSegmentedButtonRow on the feedback screen with a
FlowRow of FilterChips. The segmented button forced each option to equal
width, so longer localized labels (e.g. pt-BR "Solicitação de
aprimoramento") wrapped to multiple lines and the items rendered with
overlapping/uneven shapes. FilterChips size to their label and wrap onto a
new line when needed, fixing the layout across all locales.
