Expand Gallery functionality disco, research and design delivery

### Background
Original version of 3d Cell Viewer had a gallery-first UI. Paginated view of many thumbnails.

### User needs statement(s)
As an educator I would like to create my own set of selected cells in the dataset and be able to easily see a gallery of those cells.
As a scientist I would like to have a thumbnail gallery of any selection I make in the plot.
As a curious user I would like to be able to browse the cell thumbnails without looking at the plot. I would like to distinguish between FOV and single cell images when that is an aspect of the dataset.

### Size
m-lg

### Requirements
Paginated or scrolling view of thousands of thumbnail images when Gallery is expanded.
Ability to load albums for: currently selected cells in plot, selection sets, and "entire dataset".
I'm not sure if we should save/persist albums anywhere on behalf of users, or just "export json/load json" and let users deal with the file storage.

### Deliverables
UI designs for the above requirements

### Stakeholder(s)

### Timeline
2024?

### Notes
Technical risk: incremental fetching of 250,000+ image urls for "infinite scroll". Can we scale beyond that?
