Integrate item viewer into digital object in finding aid viewer

[mmummey-dot]

Is your feature request related to a problem? Please describe.
When I am looking at a scan in the finding aid viewer, I want the same controls as the item viewer in the web app (including download options).

Describe the solution you'd like

Describe alternatives you've considered
A link takes you to the item viewer in the web app from the finding aid viewer. Or there is a pop-up viewer with the same options as in the item viewer.

@nrsa222 I want to align on structural layout before I start writing frontend code, for the purpose of aligning on design earlier in the process. Here are two very low fidelity designs I made in excalidraw quickly. If you'd like something mirroring the final product, I can redo the mockups in figma. Feel free to send me a chat whenever you're ready to discuss.

• Layout 1: I think this first layout is simple and is an easy yes. It adds an anchor with the text "item details" below the image, which would link to the appropriate item in exploreuk-web-app
• Layout 2: This second layout adds an additional link with the text "item details" below each media item, and might be too busy. I don't want to hide the control to go to the item view behind a UI change (keeping it only in the first design), which implies some button or anchor.
• An alternate idea is to scrap lity completely, make the image link directly to the item view, and add the exact link (using anchor positioning) to the history so the back button scrolls back to the exact item in the findingaid. That would use the code I wrote to open any item directly that is already in the codebase. You'd lose the ability to flip between the images of a single component, but maybe that isn't high priority.

Screenshots of low fidelity designs below.
