Toggle VPN from Launcher/Spotlight

### Feature Description

I would like to be able to toggle VPN connection from the Launcher/Spotlight.

### Use Case

Keyboard driven toggle of VPN connection.

### Compositor(s)

All compositors

### If Other, please specify

_No response_

### Proposed Solution

No idea how the launcher/spotlight work but all configured VPN connections should be indexed and searchable.

The entry in the search results should probably look different if connected vs disconnected.

### Alternatives/Existing Solutions

_No response_

Start by locating the Launcher/Spotlight entry point and the existing handling of configured VPN connections. Determine how search results expose connection state across all compositors, then verify that VPNs can be searched and toggled and that connected and disconnected states are distinguishable.
