fix: replace hardcoded OS codename/version detection with get_os_info helpers

- checkmk: use github_api_call+jq for tag fetch, get_os_info codename in deb URL, strip +security suffix, bump default to Debian 13
- cockpit: remove source /etc/os-release, use get_os_info codename for backports suite/install, get_os_version_major for version check
- flaresolverr: replace raw grep on /etc/os-release with get_os_version_major
- lldap: remove source /etc/os-release, use get_os_info id+version for repo URL
- mqtt: remove unused source /etc/os-release
- pangolin: replace . /etc/os-release + VERSION_CODENAME with get_os_info codename
- paperless-ngx: replace both . /etc/os-release + VERSION_CODENAME checks with get_os_info codename
- photoprism: replace hardcoded bookworm in libheif URL with get_os_info codename
- proxmox-datacenter-manager: replace grep on os-release string with get_os_version_major
- wireguard: replace . /etc/os-release + VERSION_CODENAME with get_os_info codename
- zabbix: replace . /etc/os-release + VERSION_CODENAME with get_os_info codename
