Wire buyShares and menu commands, replace factory interfaces with DI

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.
