feat: implement relational lead origins with team assignments

- Dropped simple origins table in favor of origin_groups and origin_items to match the Funnels architecture.

- Added origin_group_id to teams table to assign specific origins to specific teams.

- Updated /admin/origins page to support creating origin groups, adding origin items to them, and assigning teams to groups.

- Updated Dashboard and UserDetail pages to dynamically load the exact origin items belonging to the active team/user.
