test(core): add tests for card view with edgeless mode link (#8887)

Close [BS-1881](https://linear.app/affine-design/issue/BS-1881/page内的edgeless-embed-缩放和坐标定位不太对), [BS-1907](https://linear.app/affine-design/issue/BS-1907/mode=edgeless的cardview转成embed，丢失了mode信息), related PR toeverything/blocksuite#8785, toeverything/blocksuite#8790

This PR adds a test for the fit-to-content feature of the viewport for the embed doc block in edgeless mode.
