Fix a number of frontend bugs

Data wasn't being unmarshalled in a unified way before, every page kinda does it differnetly
This means that different components on different pages have different fields missing/incorrect
Added unmarshaller for data
Used the above fix to apply a bunch of fixes to a lot of components on different pages
Fixed date prop type issue
Fixed data type passed to backend for social media is in incompatible format
Fixed frontend social media icons not displaying (socialMedia/socialMedias naming inconsistencies)
