Add daemon support for label commands and populate labels in issue queries

- Updated label CLI commands to support both daemon and direct modes
- Added label fetching to GetIssue() and scanIssues() methods
- All label operations (add, remove, list, list-all) work with daemon
- Closed bd-162 (label CLI commands), bd-166 (duplicate), bd-141 (daemon support)
