feat: Config tab "Options — Paramètres" with IV gate controls + exit params

- New tab replaces "Journal & Sortie" — consolidates all options-specific settings
- IV Gate section: toggle on/off + 3 sliders (IVR High/Extreme/Skew threshold)
  with live color-coded summary and interdependency guards (high < extreme)
- Exit params section: target, stop-loss, reversal mode + threshold (moved from removed journal tab)
- Backend: GET/PUT /api/config/options-gate endpoint reads/writes 4 config DB keys
- useApi.ts: useOptionsGate + useSaveOptionsGate hooks
