CBL Import Rework (#1862)

* Fixed a typo in a log

* Invalid XML files now "validate" correctly by sending back a failure.

* Cleaned up messaging on backend and frontend to provide some linking on series name when collision, handle corrupt xml files, etc.

* When reading list conflict occurs, show the reading list name that's conflicting. Started refactoring the code to allow multiple files to be imported at once.

* Started adding new CBL elements for some enhancements I have planned with maintainers.

* Default to empty string for IpAddress to allow to fallback into existing experience

* Tweaked the layout of reading list page (not complete), moved some not used much controls to page extras and reordered the buttons for reading list

* Edit Reading Lists now allows selection of cover image from existing items

* Fixed a bug where cover chooser base64 to image would fail to write webp files.

* Refactored the validate step to now handle multiple files in one go.

* Clean up code

* Don't show CBL name if there were xml errors that prevented showing it

* Don't allow user to go prev step after they perform the import.

* Cleaned up the heading code for accordions

* Fixed a bug with import keeping failed items

* Sort the failures to the bottom of result windows

* CBL import is pretty solid. Need one pass from Robbie on Reading List Page
