refactor: extract boxing logic into dedicated modules with tests

- boxing_models.dart: add BoxingMode, BoxingPhase, BoxingPageArguments - boxing_box_mutations.dart: box item add/replace/remove operations - boxing_calculations.dart: pure calculation helpers (quantities, validation) - boxing_status_presenter.dart: status bar text/dot determination - dialogs/cross_paichan_dialog.dart: cross-paichan confirmation dialog - widgets/boxing_notice_banners.dart: notice banner widgets - Add unit tests for mutations, calculations, and status presenter Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
