To Reproduce
Steps to reproduce the behavior:

1. Create a new CO (https://kuinvertpaleowithmigrations20241211-production.test.specifysystems.org/specify/view/collectionobject/new/)
2. See that the "Chrono Strat" query combo box does not display an IUGS chart icon
3. See that when adding a new "Chronostratigraphy" record using the query combo box there is no icon visible

Expected Behavior

It should show when entering a new Chronostrat record:

This feature was added to assist users with data entry. I think we should make this button visible in the Paleo Context subview or data entry dialog if the user prefers. Additionally, it would be helpful to include an option to disable it for those who do not use the IUGS ICC chart.
