Turn the flat sidebar into a data-driven nav: each entry declares a
group (workspace/extensions/config/dev) and a numeric priority, and each
section renders by sorting on that key. Split axis is function, not
permission — adminOnly/debugOnly gate individual entries and an empty
section is hidden, so Configuration vanishes for non-admins without a
section-level role check.
- Shared folders moves into 'Your space' (still admin-gated per-entry).
- Plugin pages merge into the workspace group on the same priority line
(>=100 by default); rebase the two in-repo plugins accordingly.
- Configuration and Development are collapsible, closed by default,
state persisted in localStorage. Simple mode unchanged.
- Rename nav.catalog to 'Connectors Catalog' to disambiguate from the
Plugin Catalog; add nav.section.* header keys (en/it/fr).
- Replace dead .sidebar-section-toggle CSS with real section classes.
