Add force sign hash wallet option

[felipemadero]

Why this should be merged

This PR introduces a ForceSignHash wallet option that enables hash-based transaction signing instead of full transaction signing. This feature is essential for:

1. Testing flexibility: Enables testing scenarios where hash-based signing is preferred or required
2. Network compatibility: CubeSigner API currently lacks network options support beyond mainnet/fuji, making hash signing necessary for other network configurations
3. Future-proofing: Provides infrastructure for advanced signing scenarios while maintaining backward compatibility

The feature is implemented as an optional wallet parameter, ensuring existing functionality remains unchanged while providing the flexibility needed for specializeduse cases.

How this works

The implementation adds a new common.WithForceSignHash() option that can be passed to any wallet transaction method:

  // Enable force sign hash for a specific transaction
  tx, err := wallet.IssueBaseTx(outputs, common.WithForceSignHash())
  // Apply force sign hash to all operations on a wallet instance
  walletWithOptions := pwallet.WithOptions(wallet, common.WithForceSignHash())

Technical Implementation:

• Added forceSignHash field to common.Options struct with corresponding getter/setter methods
• Updated both P-chain and X-chain signers to accept ...common.Option parameters
• Modified visitor structs to include forceSignHash field and use conditional signing logic
• Created WithOptions wrapper functions for signers to apply default options
• Fixed wallet WithOptions implementations to properly propagate options to signers

Signing Logic:

  var sig []byte
  if forceSignHash {
      sig, err = signer.SignHash(unsignedHash)  // Hash-based signing
  } else {
      sig, err = signer.Sign(unsignedBytes)     // Full transaction signing
  }

How this was tested

• Unit tests
• Example for testing cubesigner on a local network

Pull Request Overview

This PR introduces a ForceSignHash wallet option that enables hash-based transaction signing instead of full transaction signing for both P-chain and X-chain wallets. This feature provides testing flexibility and network compatibility for scenarios where CubeSigner API lacks network options beyond mainnet/fuji.

• Adds a new ForceSignHash option to the common options structure
• Updates both P-chain and X-chain signers to support the new signing mode
• Implements conditional signing logic that chooses between hash-based and full transaction signing
