[React] API Image Functionality (#5696)

* Improvements to API handling on react UI

- Do not force "/api/" prefix to the base URL of the server
- We will need to fetch media files from the server (at /media/)
- Extend API URL helper functions

* Update some more hard-coded URLs

* Fix search API endpoint

* Fix div for panel tab

* Fix debug msg

* Allow CORS request to /media/

* Add ApiImage component

- Used to fetch images from API which require auth
- Requires some tweaks to back-end CORS settings
- Otherwrise, image loading won't work on new API

* Update build order table

* Remove debug code

* Update part detail page
