feat: Smart Back Navigation to Accordion! 🎯

## ✅ 6. Back Button Returns to Correct Accordion

**Problem:**
- Back button used navigate(-1)
- Returned to parent page but wrong tab
- Required 2-3 clicks to get back to Email accordion
- Poor UX, confusing navigation

**Solution:**
- Back button navigates with query params
- URL: `/settings/notifications?tab={channelId}&event={eventId}`
- Templates page reads query params
- Auto-opens correct accordion
- One-click return to context

**Implementation:**

**EditTemplate.tsx:**
```tsx
onClick={() => navigate(`/settings/notifications?tab=${channelId}&event=${eventId}`)}
```

**Templates.tsx:**
```tsx
const [openAccordion, setOpenAccordion] = useState<string | undefined>();

useEffect(() => {
  const eventParam = searchParams.get(\"event\");
  if (eventParam) {
    setOpenAccordion(eventParam);
  }
}, [searchParams]);

<Accordion value={openAccordion} onValueChange={setOpenAccordion}>
```

**User Flow:**
1. User in Email accordion, editing Order Placed template
2. Clicks Back button
3. Returns to Notifications page
4. Email accordion auto-opens
5. Order Placed template visible
6. Perfect context preservation!

**Files:**
- `routes/Settings/Notifications/EditTemplate.tsx`
- `routes/Settings/Notifications/Templates.tsx`
