fix: update to @lightprotocol/stateless.js 0.22.0

- Replace deprecated defaultTestStateTreeAccounts() with selectStateTreeInfo()
- Use createRpc() without args for localnet (correct endpoint defaults)
- Update outputStateTree to outputStateTreeInfo in compress scripts
- Fix RPC endpoint configuration across all scripts
