Fix visual size matching for icons in SuggestionsPanel

- Adjust badge icons: QBZ 17px (was 22px), Qobuz 20px (was 18px)
  QBZ fills its viewBox completely while Qobuz has whitespace,
  so QBZ needs to be smaller to appear visually equal

- Adjust glyph icons: Playlist 32px (was 28px), Radio 26px (was 24px)
  Playlist SVG only fills ~77% of its 20x20 viewBox, needs larger
  pixel size to match Lucide Radio which fills its box completely
