As initially planned starting wifi only when needed, at change to HTTP mode.
Tested this on breakout board: ESP32 is not getting hot anymore!
Also optimized timeout: only notify "forgot to turn off" when battery is below certain
threshold (e.g. disable when charger is connected over night)
main:
- dont start wifi at startup anymore
- remove double-initialization of nvs
already initialized in wifi.c, thus removed some code
- optimize comments, logging
control:
- timeout "forgot to turn off": Add battery threshold
- start/stop wifi when switching to/from HTTP mode
wifi:
- split init function to separate functions for NVS and NETIF (more clear in main)
- optimize log output at nvs init (moved from main)
- rename start/stop functions, formatting
