feat(gui): docked details pane on wide windows

An adw::Breakpoint at 1000sp uncollapses the details OverlaySplitView, so
the pane sits beside the files instead of over them. The pane gains
Sharing and Versions sections, filled from ListShare and ListRevisions
when an entry is selected, with Share…, Copy Link and Versions… buttons.
