Give the collections sidebar its own Slint global

AppWindow carried the sidebar's tree, its row menu, renaming, drag and
drop between rows, the trash row, and the membership sheet as ~40
properties and callbacks on the root component, in the pattern CH-1
describes and the develop screen's globals (Adjustments, Framing, Steps,
...) already replaced. Collections.* in collections.slint now holds that
state, declared next to the MembershipRow struct it and the membership
sheet both use; Rust reaches it through window.global::<Collections>()
instead of window.set_/get_/on_/invoke_ on the root.

collection-selected, collection-select, and collection-offline-menu stay
on AppWindow: library_ui.rs invokes collection-select directly and
registers collection-offline-menu's handler, and lib.rs reads
collection-selected for back-navigation, so moving them would have meant
editing library_ui.rs, which another change on this branch is splitting
into a module directory. collections-visible stays too — it is
lib.rs's panel-layout state, seeded from the saved layout before the
sidebar exists, and collections_ui never touches it. Everything prefixed
library- (the grid's drag, selection and keyword state that the sidebar's
Rust also wires for cross-feature gestures like filing a selection into
a collection) stays on the window as well, since it belongs to the
library screen, not the sidebar.
