### Issue Description ✍️

# [Feature] Add Real-Time Candidate Management During Election Creation

## 🚀 Feature Request
Enable adding/editing candidates **directly** in the election creation form instead of requiring a separate step.

## 🤔 Current Problems
1. **Multi-step process**: Users must create election → navigate to dashboard → add candidates
2. **Poor UX**: Forces users to remember candidate details between steps
3. **Time-consuming**: Increases setup time by 3-5x

## 🎯 Desired Behavior
- ➕ **Add candidates dynamically** during form filling
- 🗑️ **Remove candidates** with one click (minimum 2 enforced)
- ✏️ **Edit details** in real-time
- ✅ **Instant validation** for:
- Minimum 2 candidates
- No empty fields
- Unique candidate names

## 📋 Requirements
### Core Functionality
- Unlimited candidate additions
- Intuitive "+ Add Candidate" button
- Delete icon per candidate row
- Real-time save state

### Validation Rules
| Validation | Error Message |
|------------|---------------|
| <2 candidates | "Minimum 2 candidates required" |
| Empty fields | "All candidates need name & description" |
| Duplicate names | "Candidate names must be unique" |

### UI/UX
- Mobile-responsive layout
- Smooth animations for add/remove actions
- Clear error states
- Visual candidate counter

## ✅ Acceptance Criteria
- [ ] Users can add candidates during form filling
- [ ] Minimum 2 candidates enforced
- [ ] All validations provide clear feedback
- [ ] Works on mobile devices
- [ ] Animations don't impact performance
