Support richer file management with support for directories

[GCHQDeveloper36]

Problem

Uploading files to an entry is done in a flat style, with no support for hierarchy or mirroring files distributed in a richer format with subdirectories for organisation.

Proposed Solution

Allow users to name files in a path-like structure (e.g. filename is subdir/file.json). When showing a list of files, show these prefixes/paths as folder-like objects that can be expanded or navigated into.

Alternatives

Prefix filenames like subdir-file.json which isn't clear, and breaks naming of files.
