Reviewer's Guide by Sourcery

This PR reorganizes and enhances the documentation structure for the perovskite solar cells database, with a focus on adding new sections about the ions database functionality. The changes include restructuring the navigation, adding new how-to guides, and updating the main documentation pages with additional information about ions and perovskite compositions.

No diagrams generated as the changes look simple and do not need a visual representation.
