Further UI renaming

[kpsherva]

On the form: https://sandbox-cds-ils.web.cern.ch/backoffice/acquisition/orders/create

Internal purchase requisition ID -> please add 'DAI' in parenthesis at the end

ID of inter-departmental transfer -> please add 'TID' in parenthesis at the end

I still see 'ebooks' in the Search bar in the front office:

ebooks -> e-books

I do not see this change. I still see 'Monographs':

Left menu:

Series / Monographs -> Series / Multipart
