Is your feature request related to a problem? Please describe. Add a UI for editing App Resources:

• [ ] Add sp7-exclusive Institutional prefs (similar to Collection Prefs added in https://github.com/specify/specify7/pull/2247) (instead of relaying on legacy Global prefs and Remote prefs) (#3169)
• [x] DataObjFormatters (https://github.com/specify/specify7/issues/23)
• [x] UIFormatters (https://github.com/specify/specify7/issues/23)
• [ ] ExpressSearchConfig (https://github.com/specify/specify7/issues/1152)
• [x] #3176
• [ ] leaflet-layers
• [ ] TypeSearches (https://github.com/specify/specify7/issues/1321)
• [x] UI for editing DialogDefs is not needed. Instead, Specify 7 should stop using that app resource (https://github.com/specify/specify7/issues/3173)

This is not done. This issue is about replacing the text editor with a better UI for editing formatters, aggregators, weblinks and the rest
