Add support for POST request with data inside query & Small fixes

[ungeskriptet]

This PR fixes the following issues I have noticed:

• Port gets stripped from URLs when using POST method
• %loc only gets replaced for $urlleave using GET method
• Refactor from execute(); to executeQuery(); to fix tests & Nextcloud 33 support

It also adds the following improvements:

• Allow replacing %lat and %lon inside $urlenter/$urlleave seperately
• Allow sending POST request data inside query instead of body

Using these additions it's possible to set the URLs to a Traccer URL from Home Assistant for presence detection.
