feat: reorganize threshold config with dot-notation grouping and enabled toggle

- Rename warningThreshold → threshold.warning, criticalThreshold → threshold.critical
- Add threshold.enabled (default: true) to allow disabling status bar coloring
- Add order fields to control display order in VS Code Settings editor
- Add order 0 to refreshIntervalMinutes for consistent ordering
