V147: Persist geo-location on known devices.

Adds a nullable `location` column to `phoenix_kit_user_known_devices`. The
"City, Country" string is already resolved at new-device time by
`PhoenixKit.Users.LoginAlerts` (it was only used in the alert email);
storing it lets the user's Active Sessions list show where each session
signed in from without an extra geo lookup per page render.
