Visualization images larger than at 1 MB solution

[hujambo-dunia]

• This is a feature enhancement request (not a bug).
• On UseGalaxy.org, SVG viz images greater than 1 MB are cropped and only text is viewable where an image should appear. There currently exists a notification (stating This dataset is large and only the first megabyte is shown below.) the above (which is good since at least user is aware).
• However, in addition now requiring the user to download the file (SVG) and find a viewing application to see their image in; this issue also breaks at least one tutorial on GTN, Bacterial Genome Annotation.
• The 1 MB restriction makes sense, especially for outputs that are just data tables. Unsure if this is just an issue with SVG images. However, for images think there needs to be a better way to handle viewing larger images.

Some possible improvements:

1. Show a thumbnail / small image version instead (but doesn't provide high resolution viewing in browser)
2. Load an image-viewer viz app that loads the image output (but this still might leave the tutorials broken). Currently, I only see an option for a viz app called "Editor" which states "manually edit text content". This might mean a change to the galaxy-charts repo.

STEPS TO REPRODUCE:

1. Go to IWC, run this workflow https://iwc.galaxyproject.org/workflow/bacterial_genome_annotation-main/
2. After run completes successfully, click bakta_annotation_plot in the History panel.
3. Will see the tag output with no options for in-browser viewing

I thought we fixed this at the hackathon at GCC -- let me find the branch. May not have made it to a PR :/
