Move project lifetime management to vue

[farmaazon]

We want to have a single Vue store which tracks the entire "lifetime" of projects opened by user, which also includes all project-specific stores (project, graph, projectNames, widgetRegistry etc.) being created when project reached "opened" state.

With that single project list, we should be able to display hybrid project tab immediately (without waiting for download). If possible, also show the proper name immediately.

As a result, we should also remove Editor.tsx react layer between AppContainer and ProjectView.

Refinement notes:

• the direct goal of this task is: move projectHooks logic to vue, and remove Editor.tsx, nicely.
• consider merging it with openProjects store and make the latter maintaining lifetime of project-related vue stores (instead of ProjectView component)

There were crucial bugs related to hybrid projects synchronization lately. This hybrid project should be taken care of in this task.
