feat(xcm): Add Pezkuwi Teyrchain junction support for cross-chain transfers

- Add TEYRCHAIN_INFO constant and TeyrchainInfo pallet lookup
- Add PezkuwiXcm pallet support in xcmPalletName functions
- Update ParachainInfoRepository to query TeyrchainId storage
- Add junctionTypeName to ParachainId for Teyrchain encoding
- Update MultiLocationEncoding to handle both Parachain and Teyrchain
- Detect Pezkuwi chains by genesis hash for correct junction type

Fixes cross-chain transfers between Pezkuwi, Asset Hub, and People chains.
