feat: add exit animations on lead cards and cross-page filter continuity

- Wrap lead cards in AnimatePresence/motion.div so they fade+slide out when removed from the NEW filter
- Update "View All" link to pass active source filter as ?source= URL param
- Initialize AllLeadsPage sourceFilter from URL search params on mount
