Avoid repeated scanning for swap trades via BsqTxListItem ctor

Browse Source 
Precompute and pass a map of txIds to BsqSwapTrade instances to the
BsqTxListItem constructor in 'BsqTxView.updateList()', in place of the
tradable repository, so that the tradables don't need to be repeatedly
scanned to find the optional matching BSQ swap trade for each BSQ tx.

This fixes a quadratic time bug and significantly speeds up the BSQ tx
view load for users with many past trades.
