deps: bump luxfi/database v1.20.3 -> v1.20.4 (prefixdb prefix-iteration fix)

database v1.20.4 fixes prefixdb NewIteratorWithStartAndPrefix synthesizing a
pre-prefix start for a nil-start prefix scan, which returned ZERO rows over a
prefixdb-wrapped store (every plugin VM's chain DB via vm/rpc) when sub-prefix
keys sorted before the target. This stranded the native D-Chain: rebuildBookFromDB
iterates order:<pool> alongside asset:/balance:/locked:/meta: rows, folded an
EMPTY book, and every taker cross produced 0 fills despite durably-committed
asks. With the bump the order book refolds correctly and crosses settle.
