model: relocate market DTOs out of the flat api package

Move AccountDTO/MarketDTO/MarketStateDTO/PurchaseReceiptDTO/TradeRowDTO
out of the catch-all api package into model.market (and LedgerDTO into
model.ledger), matching the existing model.event convention so DTOs
live next to the domain they describe rather than in the interface
package. Relocate LedgerMapper from mapper.v2 to infrastructure.adapter
to match the module's established package layout, and update all call
sites and imports accordingly.

Also register the ui-desktop module in the build tooling: add it to
MODULES, add openjfx to the shipped runtime libs, and generalize
package.sh so each executable module (ui-console, ui-desktop) gets its
own Main-Class/Class-Path manifest and run script instead of
special-casing ui-console. Fold long Class-Path manifest lines at 72
bytes per the JAR spec, since adding ui-desktop's dependencies pushed
the line past the limit.
