feat: decouple views from projects (#2217)

This PR decouples views from projects. On the surface, everything stays the same - by default, there are the same views as right now in main - List, Gantt, Table, Kanban. With this feature, it is possible to modify these or create new ones. That means you can remove views you never need or create multiple ones if you need different configurations.

Each view can have an optional filter to change what you see in the frontend on that view. For kanban, you can either set it to "manual" mode, where you can create buckets and move tasks around, or "filter" mode, where each bucket is the result of a filter (and you cannot move them around).

All positions and buckets are now tied to the view, not the project. This means you can (finally!) have views for saved filters.
