Since we have WWAN SImodule M7672G-LNGV which is not able to make the connection via modem-manager, and have no plan to upstream the change. Therefore, we need to control it via AT command
Add recovery job

Pull request overview
This PR extends the contrib CE-OEM provider with an automated WWAN connectivity and recovery test flow that drives modem bring-up via AT commands through ModemManager (mmcli --command), intended for platforms where ModemManager’s higher-level connection logic is insufficient.
Changes:
- Add a new CE-OEM WWAN automated test plan and wire it into the CE-OEM umbrella test plan.
- Introduce templated WWAN jobs gated by new manifest entries (AT-command control + optional reset/recovery).
- Add the AT-command runner script, its JSON-driven module step configuration, documentation, and unit tests.
