refactor: enhance account event parser with more precise event classification

- Rename CommonAccountEvent to TokenAccountEvent for better semantic clarity
- Rename AccountNonce to NonceAccount for consistent naming convention
- Add MintInfoEvent type to support SPL Token Mint account parsing
- Enhance parse_token_account_event to automatically detect and parse Mint accounts
- Update all example code to use new event types and structures
- Improve event type semantics for better developer experience
