feat(frontend): slice 5 — migrate Settings + Actions to shadcn/Tailwind
Web UI rework. Form-heavy pair (controlled useState parity, no form lib):
- pages/Settings.tsx off @mui: monitoring-machine CRUD, SSH-key mgmt,
SSH test/validation feedback, danger-zone reset (ConfirmDialog), tabs
- pages/Actions.tsx off @mui: saved-task editor, machine selection,
run history, tabs
- Both reuse migrated shared components (SectionCard/SelectionRailCard/
TabbedCard/HoverEditButton/ConfirmDialog/DialogFooter) as before
- Behavioral tests added (mocked hooks; no live SSH)
Gate: build + lint + test green (19 files / 39 tests).
