Fix broken file icons

Refactored image handling:

• Unified code to a single "factory"
• No longer uses store
• Using the Vite glob import instead of the webpack context
• Simpler and more automated way of choosing image format

Fixed displaying of correct file icon:

• Created ease of use functionality for getting a file icon
• Extended detection of media formats
• Removed redundant and stale code and moved it all to the image "factory"
• ResourceCard as well as EditResource now show the correct type icon

Fixed listing in ResourceCard:

• Removed all unused code in BaseIconLabelView
• Simplified Existing code using only the DOM elements necessary
• No huge gaps between icon and text
• Does not take up rest of space so hovering over empty space won't trigger tooltip anymore
• Combined display of "file" size and type
• No longer refer to resource as file
