Update all client-side permission names to match new backend

Release 1.2.0 of ui-users is out! https://github.com/folio-org/ui-users/blob/v1.2.0/CHANGELOG.md

It should work correctly in tomorrow's daily build of the test-site.

I note that no users-bl permissions are involved any more. I think this is correct, and as it should be: all the facilities used by ui-users are provided by mod-users, not by the users business-logic module.

(In a saner world, of course, the Business Logic module would provide an all-in-one create-new-user API, controlled by a single permission users-bl.user-create, to which we would pass all the relevant information in a single shot. No doubt that will turn up in due course.)

As of commit https://github.com/folio-org/ui-users/commit/0b1f376f562d9120f1a4580459cf9e64328446b4, we are finally done (for now!) on this pestilential work. So picky, so error-prone, so awkward to test, and so dependent on the shifting sands of the back-end!

I will make a new ui-users release before closing the issue, but the actual work is done.

The following permissions are now checked in the UI Users module, and have been experimentally confirmed to match the checks done in the back-end:

• users.item.post, login.item.post, perms.users.item.post – "New user" button

• users.item.put – "Edit User" button

• users.item.get – view user in right pane

• circulation.loans.collection.get – display user loan history

• perms.users.get – display user permissions

• perms.users.item.post – add a permission to a user

• perms.users.item.delete – delete a permission from a user

• perms.permissions.get – see permission sets

• perms.users.item.put – add permissions to, or remove them from, a permission set

The last of these should be perms.permissions.item.put, but the back-end checks the wrong permission. It will be corrected in a subsequent release, which will require that the Users UI module be changed again to match this.

(I thought the relevant permissions for adding permissions to, and deleting them from, a permission set were perms.permissions.item.post and perms.permissions.item.delete; but these are for creating and deleting whole permission sets.)

I think that the present git head of ui-users is now permission-compatible with folio-backend-auth v0.12.0.

Unbelievably, the permission names seem to have changed again in the newest folio-backend-auth.

I am testing and changing them all again.
