feat: add filters to url search params

[maurerle]

Description

This adds the feature of url search params to the map.
This way, any filter can be encoded in the url.

Motivation and Context

fixes #70

How Has This Been Tested?

Various filters like:
http://localhost:5173/#/en/map?node.update=deactivated&node.visible=no

http://localhost:5173/#/en/map?node.hardware=Ubiquiti+UniFi+AC+Mesh

http://localhost:5173/#/en/map?node.firmware=v2025.1.0,!v2021.1.2-16

• Selecting a node after setting filters loses the filters in the url though.

The statusFieldMapping should be improved further to not duplicate code..
