Bug 10516 - Improve titles, breadcrumbs, and confirmation messages for Z39.50 server adds and updates

The template for adding/editing Z39.50 servers shows the same title,
breadcrumbs, etc. for add and edit operations. This patch creates
separate text for each case.

To test, try both adding and editing a Z39.50 server. The page title,
breadcrumb, and heading should correctly reflect the operation you
perform.

Works nicely and all strings are translatable.

Bug 10516 - Follow up - Fixing capitalization

Fix capitalization on submit buttons when deleting
a Z39.50 server.

- Delete this Server
- Do Not Delete

I think the "Do not delete" should maybe even be a cancel
link to be more consistent with how Koha displays this
kind of dialog in other places.

Bug 10557: remove unused branch parameter from GetBooksellersWithLateOrders

C4::Booksellers::GetBooksellersWithLateOrders has an unused parameter.
The $branch variable is never used in the routine.

Test plan:
Check that no behavior changes on the late orders page.

I couldn't find any use of the branch parameter apart from
the one corrected by this patch. Also tested late orders,
couldn't find any problems.
