cli Feature Request: Ability to create folders in a collection

Checklist

[x] I've searched for similar feature requests.

Enhancement request

Currently, Httpie Desktop allows organizing requests into collections, but there is no way to further categorize them into folders. Adding support for folders within a collection would improve request organization, especially for users managing multiple related requests. …

Problem it solves

Frustration with disorganization: I'm always frustrated when my collection becomes cluttered with numerous requests, making it difficult to locate specific endpoints.
Improved organization: I’m trying to group related requests (e.g., by feature, module, or API version) so that I can maintain a clean and structured workspace.
Efficiency: This feature would save time by allowing me to quickly navigate through categorized folders instead of scrolling through a long list of requests.
