Create Contract Creation Wizard

## 📚 Overview
Design and implement a multi-step form to guide users through creating service contracts. The form will handle selecting services, defining milestones, setting terms, and confirming on the blockchain.

## 🔍 Background
Service contracts are the foundation of secure freelance transactions on SkillChain. By guiding users through a clear step-by-step creation process, we ensure structured, transparent agreements that benefit both clients and freelancers.

---

## 🛠 Requirements
- Create form under `src/components/modules/contracts`
- Implement steps:
- Service selection
- Milestone definition (`MilestoneBuilder` component)
- Contract terms
- Confirmation + blockchain transaction
- Add real-time XLM/USDC price converter
- Add preview modal for transaction
- Enable dynamic add/remove of milestones

---

## 🔧 Implementation Plan

### 1. Create Feature Branch
```bash
git checkout -b feature-contract-form-[issue-number]
```

### 2. Form Flow and Logic
- Use React state/hooks to manage form progression
- Add animated transitions between steps (e.g., Framer Motion)
- Validate fields using `Zod`
- Structure each step in its own component under `contracts/form/`

### 3. UI Components
- Build with SHADCN/UI and Tailwind CSS
- Use reusable input and validation components
- Include transaction preview modal
- Implement blockchain confirmation UI on final step

### 4. Blockchain Integration
- Add wallet requirement check before confirmation
- Show cost estimate using real-time conversion (XLM/USDC)
- Include confirmation status with visual feedback

### 5. Feedback and States
- Show smooth animated transitions between steps
- Display error states for each form section
- Show loading spinner on blockchain operations

### 6. Testing
- Unit test each form step and milestone builder
- Integration test full flow from start to confirmation
- Validate milestone addition/removal edge cases

### 7. Commit and Push
```bash
git add .
git commit -m "Feature: Multi-step Contract Creation Form"
git push origin feature-contract-form-[issue-number]
```
