This patch expands the logic around the page title and breadcrumbs of the CSV profiles page. The name of the page has also been changed from "CSV export profiles" to "CSV profiles" to match links elsewhere in Koha.
Breadcrumbs now display as:
- Initial window: Tools > CSV profiles
- New CSV profile: Tools > CSV profiles > New CSV profile
- Edit an existing CSV profile: Tools > CSV profiles > Modify a CSV profile
