UI (CSS) issues on Safari

[christad92]

For users on Safari, we have seen some CSS Issues/inconsistencies. 2% of app.openfn.org users over 90 days use Safari but these issues are very critical to the onboarding experience of users.

This was replicated on Safari: Version 18.0 (20619.1.26.31.6)

Missing/Disappeared trigger icons

Z-index for the copy/add buttons on docs panel
