* Add bulk volume editing with rich tooltip

* Add checkbox next to Volume field for enabling bulk volume editing (only in bulk mode)

* Support single number (5), range (1-10), or comma list (1, 3, 5) input formats

* Sort files alphabetically before volume assignment

* Validate that volume count matches file count

* Add rich HTML tooltip explaining the feature

* Move bulkVolumeCheck widget definition to MetaEditor.ui

* Define bulkVolumeCheck QCheckBox in MetaEditor.ui instead of creating it programmatically in KCC_gui.py

* Update tab order to include bulkVolumeCheck after volumeLine

* Multiple directories enable bulk mode with volume number assignment
* Uses Qt's built-in dialog with multi-selection enabled for native look and feel

* Fix volume input validation in bulk metadata editor

* Fix CBR read-only check in bulk metadata editor

* Check all files for CBR format during load instead of during save

* Unify the CBR check for single and bulk mode

* Code comments cleanup

* Use ExtendedSelection for multi-directory file dialog

* use !=
