Fix nftables query by using full path to nft binary

Use explicit path /run/current-system/sw/bin/nft to match sudoers
configuration. Previously using 'nft' without path was resolving to
wrong location and failing permission checks.

- Change from 'sudo nft' to 'sudo /run/current-system/sw/bin/nft'
- Matches sudoers entry for passwordless execution
- Update version to v0.1.255
