feat: implement DUST generation methods and explicit variable passing

- Add fundWallet method for funding wallets with Night tokens
- Add showWallet method for checking wallet state including DUST UTXOs
- Add generateDust method for complete DUST generation workflow
- Add comprehensive e2e test for DUST generation workflow
- Fix JSON parsing for wallet state output with proper regex matching
- Remove interface duplication by extending ToolkitTransactionResult
- Restructure test to use beforeAll hooks for data execution
- Use test blocks for verification only
- Implement clear data flow between test steps:
  * Step 1: fundingResult from fundWallet()
  * Step 2: walletStateAfterFunding from showWallet()
  * Step 3: dustGenerationResult from generateDust()
  * Step 4: finalWalletState with cross-referencing
- All tests passing with explicit variable passing
- Clean up codebase with TypeScript implementation
