Add 1Password 1PUX and Bitwarden JSON Importers

* Closes #7545 - Support 1Password 1PUX import format based on https://support.1password.com/1pux-format/

* Closes #8367 - Support Bitwarden JSON import format (both unencrypted and encrypted) based on https://bitwarden.com/help/encrypted-export/

* Fixes #9577 - OPVault import when fields have the same name or type

* Introduce the import wizard to handle all import tasks (CSV, KDBX1, OPVault, 1PUX, JSON)

* Clean up CSV parser code to make it much more efficient and easier to read

* Combine all importer tests (except CSV) into one test file
