DOI metadata import for sharing existing research articles

[ivanminutillo]

For this feature, the platform will need to be able to fetch metadata from a DOI (Digital Object Identifier). This process involves using APIs to gather bibliographic details, such as the title, authors, abstract, publication date, and publisher. Once imported, this metadata can be used to create a new post or update an existing one, making it easy for researchers to share and discuss existing research articles.
