Easily add documentation to Grottocenter

We are committed to making life easier for Grottocenter contributors, and a key aspect of this is linking caves to the documents that describe them. It is a highly effective way to provide comprehensive information and offer access to cave surveys or field reports. The process is now much simpler: you can specify the relevant cave entrances directly from a document's page.
Furthermore, you can preview documents from an entrance's page before linking them, ensuring accuracy.
Moderator workflows have also been streamlined thanks to an improved interface.
