[Refactor] Serial generation (#8246)

* Refactor "update_serial_number" method

* Refactor serial number validation

- Query is much more efficient now
- Does not have to check each serial number individually
- Makes use of existing Part class method

* Refactor creation of multiple stock items

* Fix for singular item creation

* Refactor serializeStock method:

- Push "rebuild tree" to background worker
- Use bulk_create actions

* Refactor createion of serialized build outputs

* Prevent 1+N DB hits

* Cleanup

* Cleanup

* Reinstate serial number checks

* Add limit for serial number extraction

* Fix cache config

* Revert cache settings

* Fix for unit tests

* Playwright tests

* Bug fix

* Force False cookie mode in testing

* Revert aria-label for PanelGroup items

- No longer works as expected with playwright locators

* Fix playwright vtest

* Further updates

* Playwright test adjustments

* Remove duplicate locator
