Fix image_data column in "projects" table & project image render on frontend

[vicente6j]

(Slightly urgent)
In trying to improve UX in the PortalProjects page, I added a column to support image_data as a string with a character limit of 1 million (see the most recent push on dev). However, in trying to display the image it won't render it properly.

Hence to-do number 1 is to fix the rendering of the image on a ProjectCard. Does it have to do with unsupported file formats?

To-do number 2 is to understand what the issue is with the image_data column. If you try and boot this up in Postgres on your terminal and run select * from "projects", you'll find that nothing is displayed. But you can select individual columns. This is of course not what we would like.

Only listed as mildly urgent as having an image for a project would be nice, but is not absolutely critical to the logic of project applications.
