feat: improve Jitsi Meet interaction and room naming

- Enable pointer events on iframe for direct mouse/touch/pen interaction
- Room names now use canvas slug (e.g., mycofi-jeffsi-meet for /mycofi)
- All video chats in same canvas room share the same Jitsi room
- Support both /:slug and /board/:slug URL patterns
