Organisation Settings - Restricting overriding of organisation/project settings

### Problem Statement Restricting access to sensitive settings: For example, allowing only specific roles to update project rate limits. This ensures critical configurations are protected and minimizes accidental changes by unauthorized users. Configuring permissions for API interactions: Restrict project settings modifications through the API to prevent overrides made by unauthorized teams, even when using Terraform. Use Case: Organizations that are primarily using Terraform for Sentry configuration. However, teams can override these settings via the API. Adding RBAC would allow fine-grained permissions to control who can make such changes, ensuring a secure and governed setup. ### Solution Brainstorm _No response_ ### Product Area Settings - General
