library: seed label templates/layouts, default item type, fix Apache setup

- Seed Avery 5160/5167 and Demco spine templates plus Spine, Spine+barcode
  and Barcode-only layouts (Dewey call number split across lines)
- Default 942$c (item type) to BOOK so a Z39.50 import saves without edits
- Enable Plack includes in addition to the plain ones (static files/rewrites)
- Swap Apache from mpm_itk to prefork after koha-create (itk can't switch
  users in a container and returned HTTP 500 on every page)
- Drop unneeded SETUID/SETGID caps

Verified live: staff login, Z39.50 search/import against a local server,
save + auto barcode, label PDF with Dewey spine + barcode.
