These three methods were defined with `raise NotImplementedError` in
AccessPointDriver. Because AccessPointDriver appears before the mixin
classes in the MRO of concrete drivers (e.g. OpenWrtDriver), this caused
the abstract body to be called instead of the mixin implementation.
Symptoms:
- get_radio_status() → NotImplementedError, silently caught in poll →
radio_snapshot never updated after the initial snap
- get_ssids() / get_wireless_clients() → same silent failure
Fix: remove the method bodies from AccessPointDriver entirely. Python then
continues the MRO search and finds the correct mixin implementation.
The comment documents the invariant so it is not accidentally re-introduced.
