fix(gui): readable Environment dropdowns and action buttons — 0.10.1

- Style the QComboBox popup (QAbstractItemView) — it's a separate widget the
  theme didn't cover, so the drop-down list rendered light-on-light.
- Install/Apply finding buttons used PrimaryButton (accent fill + dark text),
  whose fill didn't paint reliably inside the finding cards, leaving dim
  dark-on-dark text. New outlined ActionButton style: bright accent text on the
  dark card, fills accent on hover, with a min-height so the row can't crush it.
