fix(meta): show image preview

[seaerchin]

Problem

Right now on studio, we don't show the meta image on upload. this PR implements a simple preview for meta image.

Solution

1. add a meta format inside our components. this is required because we use json forms to render our meta settings but we don't have a preview
2. in our renderers, add a meta renderer that uses the retry strategy in the base branch. we render the preview right below (pending design comments omegalul)

Tests

1. create a page
2. go to the meta settings
3. upload an image
4. the image should render after a while
5. delete the image
6. upload another image
7. the new image should render
