TODO: Store pending tokens for recovery

Priority

🟡 Medium Priority - Improves reliability

Current Code

# Mark the consumed input proofs as spent (not the output proofs!)
# This creates proper NIP-60 state transitions with rollover events
await self._mark_proofs_as_spent(consumed_proofs)

# Note: Spending history is now created automatically in _mark_proofs_as_spent
# TODO: store pending token somewhere to check on status and potentially undo

What needs to be done

• Store created tokens temporarily before they're claimed by recipient
• Enable status checking and potential recovery/undo
• Implement timeout mechanism for unclaimed tokens

Approach

1. Store token + metadata in local cache/file
2. Track creation timestamp and expiry
3. Provide API to check token status
4. Implement recovery for expired tokens
