AIP-68 Add react plugins to Dashboard Overview pages

[bbovenzi]

Description

In #53377 we added react plugins to the nav bar and dag tabs as their own contained views. Next up, we want to add react plugins into our dashboard as one component among many.

This also requires some refactoring of the layout of each page to support a component of unknown size being added.

Ideally, we use a flex grid or flex container and allow a plugin developer to use only css to specify the order positioning of their component without the plugin manager needing any additional fields.

dashboard is done as part of: #54131

I used a simple flexblox to place vertically in the dashboard page. If we need a more finned grain positioning, we can refactor with a css grid.

I'll split that issue
