feat: implement advanced funnel management with multiple funnels and team assignments

- Updated DB schema to support multiple funnels (funnels table) and their stages (funnel_stages table).

- Added funnel_id to teams table to link teams to specific funnels.

- Redesigned /admin/funnels page ('Meus Funis') to allow creating multiple funnels, managing their stages, and assigning them to teams.

- Updated Dashboard, UserDetail, and AttendanceDetail to dynamically load the correct funnel based on the selected team or user's assigned team.
