Update node configs: optimize pruning, disable external ports

- Remove 9944/9615 from external firewall ports (localhost only)
- Add pruning flags for para and relay chains (--blocks-pruning=256, --state-pruning=256)
- Use --database=paritydb and --sync=fast for collators
- Disable relay chain RPC with --rpc-port=0
- Add --pool-limit=0 for relay chain on collators
- Replace archive-canonical with pruned relay chain config
- Add chown root:root for binary ownership
