fix: update lint script and molecule configs for CI

- Add project-level .ansible-lint with profile:min and skip_list for
  pre-existing issues (fqcn, name casing, truthy, octal, etc.)
- Rewrite lint script to run from project root using project config
- Remove per-role .ansible-lint files (conflicted with v26 syntax)
- Molecule: drop Ubuntu 20.04 platforms (EOL), keep 22.04 only
- Molecule: use cgroupns_mode:host instead of cgroup v1 bind mount
- Molecule: remove command:/sbin/init and tmpfs that caused systemd
  to clean /tmp and break Ansible temp dir creation
- Molecule: add privileged:true where missing, remove max-parallel
  limit, set fail-fast:false, upgrade runner to ubuntu-24.04
- Add ANSIBLE_ROLES_PATH to molecule workflow so roles are discoverable
