"Automatically block the last IP address used by this user, and any subsequent IP addresses they try to edit from" should be disabled and not hidden when targeting ip/ip-range to unify the user experience**Problem**
As are suppression checkboxSpecial:Block has an outdated UI behavior where some checkboxes will hide/show based on the configuration of the block. Current Wikimedia interface design standards dictate these options should be enable/disabled.
No defaults/behavior should change other than from hide/show to disable/enable------
**Solution**
Where the checkbox is never visible to a particular admin because they don't have the correct permissions, it should remain never visible to them.
Where a checkbox can be visible to an admin if they enter certain parameters, it should go between enabled/disabled instead of shown and hidden. (It should probably also be appropriately checked if disabled, so that the admin can understand what the block will do.)
------
**Acceptance criteria**
* The `Automatically block the last IP address used by this user, [...]` checkbox behavior should be changed from hide/show to enable/disable
* The `Hide this username` checkbox behavior should be changed from hide/show to enable/disable
* No defaults or behaviors should change other than the aforementioned UI changes.
** e.g. the `Hide this username` should only appear to users with the appropriate permissions
** e.g. the `Automatically block the last IP` should only be enabled if a username is provided
