Subject: [PATCH] fix: resolve best practice and lint violations

- Convert ~290 short module names to FQCNs across all roles
- Change become: yes/no to become: true/false, gather_facts: no to false
- Remove deprecated inject_facts_as_vars from ansible.cfg
- Add missing task names to import_tasks/include_role calls
- Add become: yes to librenms clone task (partial-become fix)
- Add pipefail to risky shell command in udp-gro-fix.yml
- Quote all octal mode values
- Harden .ansible-lint with production profile and empty skip_list
- Update findings.md with all fixes
