No Vendor opens the work order form on vendor assignment and Vendor Conflict
links each work order, as the vendor reminders did. Header baselines include the
notification bell, and the top bar user menu moves to its own component to stay
within the function-size gate. The vendor e2e now covers the feed contract.
Header bell panel and /notifications page share one feed from GET /api/notifications: labeled sections with live counts, unread styling, session-only dismiss and clear all (acknowledge rows excluded), and deep links to the unassigned queue and a work order's tab via ?wo=&tab=.
