Add humidity fan controller for toilet, tweak bathroom to match

Turns out WiFi reception here is even worse than in the bathroom. By
switching to esp-idf framework, turning off low power mode *and* setting
the preferred BSSID manually, it does actually work.

Update the bathroom to match. Untested until that actually does get back
on the network, or I go prod at it with a serial cable...
