7-sub sprint UI residual: footer login + kalendar CRUD + notif center + CRM extra tabs

A: shared/sidebar.js footer onclick → handleFootClick (Guest→/sport/login, logged-in→logout()), a11y role+keyboard, popup link fix
B: app.html SECTIONS['kalendar'] kalOpenModal/Save/Edit/Delete + Akcije kolona, mock savez:kalendar maknut
C: app.html renderNotifCenter() (sve 4 role) + sidebar bell unread badge (30s poll)
F: crm_v2.html +443 linija — Članarine, Liječnički, Obrasci tabovi (split view + dynamic schema modal)
G: index.html minor + sidebar dokumenti link refresh

Note: backend (kalendar_router, notif_router, crm_router, erp_full_router uploads, dokumenti unified) već u commit f7b5114.
