Groups them with the other event-domain enums instead of the general
api package, and updates all call sites accordingly.

state I/O
Adds a full pre-load validation pass for GM XML seeds (ids, names,
options, commission, LMSR liquidity), replaces IO.print with
System.out, and surfaces detailed error messages across load/save
commands instead of generic failures.

- Event ledger now grows on purchase and shrinks on payout, mirroring
the exact amounts moved on the buyer's ledger (it previously had a
Ledger object that nothing ever wrote to).
- Settlement and event-detail views now show the winning market's
display name instead of its raw key; event details are viewable for
settled events too (the picker previously excluded anything not
ACTIVE).
- LMSR events seed their ledger with a SUBSIDY entry for the market
maker's worst-case loss (b * ln(outcomes)), reusing the existing
cost() function rather than recomputing the formula.

Move XML loading infrastructure and models under service/catalog, and
split order execution into a real pipeline: RiskEngine checks the order,
MatchingEngine matches it, FulfillmentContext books the resulting trades,
and SettlementContext resolves winning markets. GuessMarketContext.buyShares
becomes placeOrder(price, quantity), and TradingMechanism.buy now returns
matched trades directly instead of a single TradeExecution.

Moves Event/Ledger DTOs out of the flat api package into
api/model/{event,ledger}, and moves LocalCatalogContext and order
matching logic into dedicated service/catalog and service/matching
packages, replacing TradingOperation/TradingOperationImpl.

Split GuessMarketContext into a separate CatalogContext for read-only
event listing, wrap fallible operations in Result<T> instead of throwing,
and wire load/save of events and users through a JSON Wrapper.

Implement LocalGuessMarketContext.buyShares/loadEvents via a new
TradingOperation and Loader, backed by in-memory repositories. Replace
the ConsoleInputProviderFactory/ConsoleOutputProviderFactory pattern
with picocontainer-injected providers, and drive the menu from a list
of MenuCommand implementations instead of a hardcoded printout.

GuessMarketContext gained a richer surface (loadEvents/listEvents/
buyShares/closeEvent/account/save-restoreState) backed by new
EventDetailDTO, MarketStateDTO, OptionStateDTO and PurchaseReceiptDTO.
The old engine-module provider implemented the previous shape and is
removed; market.guess.service.LocalGuessMarketContext replaces it as a
stub, each method throwing UnsupportedOperationException pending a
real implementation.

Introduce MechanismType and rename CommissionChargeType to
CommissionTiming to better describe LMSR vs order-book events.
LocalGuessMarketContext.GetAllEventsAsync is stubbed pending the new
mapping.

InputProvider/OutputProvider were api-layer types only ever implemented
by the console UI; relocate them there. Drop the unused
GuessMarketEngine/LocalGuessMarketService pair, flesh out LoadResultDTO
with success/failure variants, and make LocalGuessMarketContext.LoadAsync
report real outcomes instead of an empty placeholder.

PicoContainer wiring
Relocates GuessMarketEngine/GuessMarketContext into market.guess.api so
engine and ui-console depend on a shared contract instead of engine
internals, and makes context loading async (CompletableFuture). Adds
InputProvider/OutputProvider interfaces with console implementations,
wires the console app's Menu through a PicoContainer, and adds the
generated model classes plus vendored picocontainer jar needed to build it.

Move api, engine, ui-console and ui-desktop out of modules/ up to the
repo root and drop the empty exception project (GuessMarketException now
lives in api).
Vendor gson, jaxb, okhttp, openjfx and tomcat under lib/, and group the
JUnit standalone jar into lib/junit/ alongside them.
Rewrite every .classpath: drop the copy-pasted optional="true" that was
masking real build path errors, point the library entries at ../lib/,
and put the JUnit jar on the test source folders so the placeholder
AppTest classes compile.
ui-desktop: take the JavaFX jars off the modulepath (there is no
module-info.java, so module="true" left the packages unresolvable) and
add a Launcher that calls Application.launch, avoiding the "JavaFX
runtime components are missing" check without VM arguments.
engine: add LocalGuessMarketService and the GuessMarketContext provider
interface, and give GuessMarketException the no-arg and cause
constructors they need.
