Bug 23447: Fix capitalization and other minor edits on patron batch edit template

Just some small fixes:

- Category => Patron category (more specific for translation)
- Attribute => Patron attribute
- Opac Note => OPAC note
- Add missing colons (:) after some of the labels

To test:
- Find an existing cardnumber
- Go to Tools > Patron batch modification
- Use cardnumber in input field and continue
- Verify strings show as noted above
- Apply patch
- Repeat and verify strings have changed, everything still works
