feat: synchronize dashboard origins with management page and add integration endpoints

- Updated Dashboard origin chart to strictly reflect only configured origins, grouping unmapped data into an 'Outros' category.

- Added GET /api/integration/funnels and GET /api/integration/origins endpoints to allow external AIs to dynamically map stages and lead sources.
