Tony 5f72264b06 feat: add organization management features and password reset functionality
- Introduced a new section for managing organizations, including creating organizations and adding users to them.
- Added a password reset modal and functionality to request a password reset link.
- Updated the settings page to include personal settings for changing passwords and admin settings for configuring registration options.
- Enhanced the app detail view with tabs for releases, insights, collaborators, tracks, and settings.
- Improved user management with admin capabilities to verify user emails and change user roles.
- Updated navigation and UI elements to accommodate new features and improve user experience.
