[Delivers #43807701] Digital objects in the public app

- cleaned up the file structure in the public app, namely for the view.
- also introduced a controller for search and one for the record show pages (in prep for refactor and performance enhancement of code)
- tweaked the CSS/look and feel to use the new logo and match the staff vibe
- made digital objects available via the searches and those resources/archival objects that link to the them as an instance.
- also fixed a bug with the linker that was using the asterisk icon instead of our delegated icon
