🚀 Feature: Central Visual Editor for User Team Roles

### 🔖 Feature description Currently, roles in Appwrite are created only when adding a member to a team, which can make them seem abstract and difficult to manage. It would be helpful to have a central visual editor for roles that would allow for clear definition and easy access to existing roles. ### 🎤 Pitch The editor could be accessible through a sub-tab in the Authentication section of the Appwrite Console. From there, users could create, edit, and delete roles, as well as define the permissions associated with each role. When adding a member to a team, users could then search for and select existing roles from a drop-down menu, rather than having to create new roles each time. ### 👀 Have you spent some time to check if this issue has been raised before? - [X] I checked and didn't find similar issue ### 🏢 Have you read the Code of Conduct? - [X] I have read the [Code of Conduct](https://github.com/appwrite/.github/blob/main/CODE_OF_CONDUCT.md)
