[Bug] "Library" sidebar nav item points to non-existent view

[d-oit]

Description

The SidebarNav component (src/components/SidebarNav.tsx) includes a "Library" navigation item, but no Library view component exists in the codebase. Clicking this nav item either does nothing or causes a routing error.

Impact

• Users see a "Library" nav item that does not work
• Confusing UX — appears broken
• Could cause runtime errors depending on routing setup

Recommended Fix

Option A: Remove the "Library" nav item until the view is implemented
Option B: Implement a basic Library view (list of all entities with filters)

Acceptance Criteria

• Either "Library" view is implemented or the nav item is removed
• No broken navigation links in the sidebar
• E2E test verifies all sidebar nav items navigate correctly
