Console open state should be preserved when project persisted

Right now, the console is always closed when a project is loaded, even if it was open last time that project was modified. This is different from other UI components, whose minimization state is retained when a project is persisted and then loaded.

This is because the collection of minimized components is represented as a set of component names. This is fine as far as it goes, but it precludes adding new minimized components that are minimized by default (e.g. the console), because the absence of the console from the array in a saved project might mean either:

1. The console is not minimized in this project, or
2. The project was last saved before the console feature was introduced

To work around this, when loading a project from storage, we assume the second case and always add the console to the list of minimized components.

Instead, we should store the collection of minimized components as a Map whose keys are component names, and values are either true or false. Entries should only be present in the map if the user has explicitly hidden or shown a component; if an entry is not present, the appropriate default for the editor in question can be used (this logic should probably live in the React component layer).

首先跟踪项目的持久化和加载，然后检查应用最小化组件默认值的 React 组件层。确认已保存的最小化组件集合如何被序列化和恢复。完成的标准是：明确隐藏或显示的状态能够持久保存，而缺失的条目使用每个编辑器的默认值，包括控制台。
