### ✅ Task 2: Fix Voting Page Logic
**Status**: COMPLETE

**File**: `/frontend/app/dashboard/votes/active/[id]/page.tsx`

**Changes Made**:

#### **Before Behavior**:
```
When user visits voting page:
1. Loading spinner appears
2. Election details shown
3. If already voted → "Vote Done" message shown BELOW voting details
4. Voting form still visible below
```

#### **After Behavior** (NEW):
```
When user visits voting page:
1. Loading spinner appears ✅
2. [IF ALREADY VOTED] → Immediately return "Done" page
   - Full election details displayed
   - Green "Vote enregistré ✓" message
   - Link to blockchain
   - NO voting form shown
3. [IF NOT VOTED] → Continue to normal page
   - Full election details
   - Voting form
4. [IF ELECTION CLOSED] → Show "Closed" message
   - NO voting form
```

**Key Improvement**:
```typescript
// NEW: Early return for already-voted users
if (hasVoted && election) {
  return (
    <div className="space-y-8">
      {/* Complete vote done page */}
      {/* All election info + success message */}
    </div>
  )
}

// OLD: Conditional rendering
{!hasVoted && election.is_active ? (
  <VotingForm />
) : hasVoted ? (
  <VoteDoneMessage />
) : (
  <ElectionClosedMessage />
)}
```

**Benefits**:
- ✅ Users who voted don't see the form
- ✅ Cleaner UI - no unnecessary elements
- ✅ Faster rendering - fewer DOM elements
- ✅ Better UX - clear message: "You already voted"
- ✅ Professional appearance

**Test Scenarios**:

**Scenario 1: User hasn't voted yet**
```
Action: Click voting page
Result:
  ✅ Shows election details
  ✅ Shows voting form
  ✅ Form is active and ready
```

**Scenario 2: User has already voted**
```
Action: Click voting page
Result:
  ✅ Shows "Vote Done" page immediately
  ✅ Shows election details
  ✅ Shows success message: "Vote enregistré ✓"
  ✅ NO voting form visible
  ✅ Link to blockchain available
```

**Scenario 3: User reloads page after voting**
```
Action: F5 / Refresh
Result:
  ✅ App detects already voted
  ✅ Shows "Vote Done" page immediately
  ✅ No flash of voting form
```
