fix: correct Ed25519/Sr25519 key scheme detection for Asset Hub

- Fix RuntimeResolver prefix matching order: check asset-hub-pezkuwichain
  BEFORE asset-hub-pezkuwi to avoid false matches
- Fix zombienet SDK is_asset_hub_pezkuwi detection to exclude pezkuwichain
- Add zombienet-local-21.toml and zombienet-mainnet-21.toml configs
- Update .gitignore for sensitive mainnet files
