- DevDashboardGate intercepts left-clicks on links resolving to / and asks
before navigating; the dev-mode dashboard render takes ~100s while the
browser aborts at ~60s, so links otherwise look like a hang
- mounted only when NODE_ENV is development and a user is logged in;
modifier-clicks, new-tab and download anchors bypass the gate
- layout now imports canAccessAdminPanel from divisionAccess
