Implement Zero-Knowledge proof of payment (zk-SNARK)

This PR implements privacy-preserving proof of payment functionality using Soroban — allowing a user to prove they made a payment of at least a certain amount without revealing the exact amount or their identity to third parties.

## Features Implemented
- ✅ PaymentCommitment struct for storing commitment hashes on-chain
- ✅ ZKProof struct for zero-knowledge proof verification
- ✅ commit_payment function to store payment commitments
- ✅ verify_payment function to verify ZK proofs without revealing amounts
- ✅ Simplified Merkle tree structure for commitment storage
- ✅ TypeScript helper in lib/stellar.ts for client-side proof generation
- ✅ Comprehensive test suite for ZK proof functionality
- ✅ Double-spending prevention using nullifiers
- ✅ Privacy preservation through cryptographic commitments

## Acceptance Criteria Met
- ✅ cargo test passes for ZK proof tests
- ✅ Commitment stored on-chain without revealing amount
- ✅ verify_payment returns true for valid proofs
- ✅ verify_payment returns false for tampered proofs
- ✅ TypeScript helper generates valid proofs

## Files Modified
- contracts/stellar-micropay-contract/src/lib.rs - Main contract with ZK functionality
- lib/stellar.ts - TypeScript helper for client-side proof generation
- package.json - Dependencies for TypeScript helper
- ZK_PROOF_IMPLEMENTATION.md - Detailed implementation documentation

## Testing
All tests pass and cover:
- Valid proof verification
- Invalid proof rejection
- Double-spending prevention
- Merkle tree functionality
- Commitment hash generation
- Amount commitment verification

## Security Features
- Nullifier tracking prevents double-spending
- Cryptographic commitments hide payment amounts
- Merkle proofs provide inclusion verification
- Salt ensures uniqueness of commitments
