* vars/main.yml: header was 'vars file for homarr' (copy-paste from the
homarr role). Fixed to 'vars file for opnform'. File body is empty.
* meta/main.yml: replace ansible-galaxy init boilerplate with real
metadata — author, description, license (MIT-0), min_ansible_version
set to '2.15' as a string (galaxy schema requires str), galaxy_tags
for discovery, and an empty dependencies list.
The third inline finding (dead roles/opnform/templates/compose.yml.j2)
is resolved by dropping the WIP commit a6f301e during the rebase rather
than removing it in a separate commit — the file no longer exists in
the rebased history.
