Bug 34405: Fix inconsistencies in EDI accounts/Library EAN page titles, breadcrumbs, and headers

This patch fixes some inconsistencies in templates for EDI accounts
and Library EANs, making sure the page title, breadcrumb navigation, and
page headers are consistent with each other.

To test, apply the patch and check these views:

- Administration -> EDI accounts
  - New EDI account
  - Edit EDI account
  - Confirm deletion of EDI account
- Administration -> Library EANs
  - New library EAN
  - Edit library EAN
  - Confirm deletion of EDI account
    - With an account for a specific library
    - With an account for any library
