Before: the project detail's right-hand sidebar was one scrolling column of
properties, description and resources.
After: the sidebar has a tab strip: Properties (the existing column), then
Overview, Automations, Library and PRs. The four project-wide panels are
mounted only while selected; they render empty until each lands.
How: ProjectSidebarTabs wraps the properties column and the panels in the
shared Tabs primitive; AnimatedRightSidebar gains `padded={false}` so the
tabs own padding and scrolling. The mobile sheet renders the same tabs.
