refactor(dokploy): restrict license key access to owners only and enhance validation

- Updated the license key settings to ensure only users with the "owner" role can access certain functionalities.
- Modified the license key activation input validation to require a non-empty string.
- Improved error handling for network issues when validating license keys, providing clearer feedback to users.
- Adjusted the dashboard settings to redirect non-owner users appropriately.
