feat: implement device filtering based on GisSystemStatic Allow property

- Add Allow=1 filter in createAndSetDevices.js to hide devices with Allow=0
- Update mapLayersSlice.js setInitialLayers to respect Allow values for visibility
- Modify MapLayersControlPanel.js localStorage initialization to set visibility based on Allow property
- Only systems with Allow=1 are now visible by default, Allow=0 systems are hidden
- Ensures consistent filtering across device markers and layer visibility controls

This change addresses the requirement to hide stations/devices when their corresponding
IdSystem in GisSystemStatic.json has Allow=0, improving the map display by showing
only authorized/allowed systems to users.
