feat(environment): introduce isDefault flag for environments

- Added `isDefault` boolean column to the environment schema, defaulting to false.
- Updated environment creation and deletion logic to handle default environments, allowing the production environment to be created and renamed.
- Enhanced error handling for environment updates and deletions to prevent modifications to default environments.
- Updated UI components to reflect changes in environment selection based on the new default logic.
