Task/Issue URL: https://app.asana.com/0/1209121419454298/1204477720783181

Description:

Fix tabbing between text fields in the password manager by manually recalculating key view loop in PasswordManagementViewController. This isn't done automatically as MainWindow disables autorecalculatesKeyViewLoop.

Optional E2E tests:

• Run PIR E2E tests
  Check this to run the Personal Information Removal end to end tests. If updating CCF, or any PIR related code, tick this.

This was already approved in #3842. Recreated the PR to not use a fork so that tests run per @ayoy’s suggestion.
