Refactor lmn_wlan role

- Consolidate `lmn_wlan`, `lmn_wlan_nm`, and `lmn_wlan_8021x` into single `lmn_wlan` role.
- Implement a check for the availability of the radius-server during the EAP-TLS rollout.
- Enhance variable support with a standardized naming schema:
    - Mode selection via `wlan` variable (`none`, `psk`, `eap-tls`).
    - EAP-TLS CA configuration (CA information, email address, CA password).
    - Introduce a switch to force the (re-)issue of existing certificates.
    - PSK configuration through `wlan_ssid` and `wlan_password`.
- Add a check to verify if the radius certificate is revoked.
- Ensure required packages and services are only installed and configured if the `wifi` variable is set.
