refactor: migrate UTXO components to standalone github.com/luxfi/utxo

One place, one way to define UTXO primitives. Delete the in-tree duplicate
at node/vms/components/lux/ and import the standalone luxfi/utxo package
with a 'lux' alias so existing call-sites (lux.UTXO, lux.TransferableInput,
etc.) remain unchanged in consumers.

Files changed: 167 imports rewritten, 2 directories deleted.

Build still green on the whole tree except pre-existing examples/multi-network
QChainMainnetID issue (unrelated).

Next: rename luxfi/utxo/luxmock → utxomock for full brand-neutrality; that
is a separate PR since it requires touching all consumer alias names.
