fix: workflow failures - cargo fmt, taplo fmt, and StakingConfig

- Update taplo.toml exclude patterns to use glob patterns for zombienet files
- Add StakingConfig to genesis_config_presets for proper era initialization
- Fix cargo fmt issues in identity-kyc pallet and pezkuwichain runtime
- Set num_cores to 2 for system teyrchains (Asset Hub + People Chain)
