Move Context fields to be part of Profile Settings

[SimoneZaza]

Description

As a user, it is currently not very clear to me what this context page is, where it's content is visible, and where I can edit the things I see in the about dialog.

Acceptance criteria

For both Spaces and Subspaces,

• [ ] Move Context fields to be part as the profile page, as per design
• Vision --> What
