feat: Add fullSyncByDefault to Pezkuwi chains and fix chain sorting

- Added fullSyncByDefault option to all Pezkuwi chains (mainnet, Asset Hub,
  People, Zagros) to enable automatic balance sync
- Fixed chain sorting to include Polkadot and Kusama relay chains
- Pezkuwi ecosystem now correctly appears first in network lists
