feat: add wallet generation to deployment script

- Generate wallet with private/public keys during node deployment
- Create genesis allocation file with wallet address and initial coins
- Wallet receives 1 billion tokens from genesis block
- Save wallet to keystore for later use
- Replace genesis block generation with wallet+genesis generation
