Fix external components

[kr0ner]

Local copy of the git repo made it look like it works ... It did not!
Anyways it is much cleaner now and I finally got rid of the custom components.

i have a error:

INFO ESPHome 2026.3.1
INFO Reading configuration /config/esphome/waermepumpe.yaml...
INFO Unable to import component wp_core: No module named 'esphome.components.wp_core'

@Nebnenut you need to align your yaml in esphome root to either use the local components or the ones, like in standalone yaml, that get fetched directly from github 😉

I didn't verify the changes in the YAML file.

It's working now; please adjust the length of the SSID, which can be a maximum of 32 characters.

 ap: 
    
    SSID can't be longer than 32 characters.
