feat: show siderolink status on dashboard

Add a new resource, `SiderolinkStatus`, which combines the following info:
- The Siderolink API endpoint without the query parameters or fragments (potentially sensitive info due to the join token)
- The status of the Siderolink connection

This resource is not set as sensitive, so it can be retrieved by the users with `os:operator` role (e.g., using `talosctl dashboard` through Omni).

Make use of this resource in the dashboard to display the status of the Siderolink connection.

Additionally, rework the status columns in the dashboard to:
- Display a Linux terminal compatible "tick" or a "cross" prefix for statuses in addition to the red/green color coding.
- Move and combine some statuses to save rows and make them more even.

Closes siderolabs/talos#8643.
