fix: Add safety improvements for swap and XCM functionality

- Add independent chain warm-up with error handling
- Add fallback fee estimation when dry run fails
- Handle empty forwarded XCMs in dry run gracefully
- Support both legacy and new XCM config destination formats
- Use xcmPalletNameOrNull for safer pallet detection
- Add Teyrchain junction support for legacy cross-chain config
- Recover from dry run failures in cross-chain transfers
- Add Pezkuwi Asset Hub to swap warm-up chains
