feat(todo): the open sidebar lists favourites and the project tree, folds kept

Browse source 
Todo's open sidebar is laid out as Todoist's (the developer's decisions
of 10 Nov 2026): the favourite projects, filters and labels, then the
projects as a tree with their open counts, sub-projects folding. Browse
and the sidebar share their rows (project_lists.dart) and their folds,
which the device now keeps per person (FoldedProjects,
folded_projects.json in the person's folder) instead of forgetting them
at each start.

Whats-New: On a wide screen, the open sidebar lists your favourites and projects; folded sub-projects stay folded.
Whats-New-De: Auf breiten Bildschirmen zeigt die geöffnete Seitenleiste deine Favoriten und Projekte; eingeklappte Unterprojekte bleiben eingeklappt.
