Renames the rover-location status enum and every label that referenced it. Existing rows are migrated in place. Also touches the consumers: - Rover.Location enum + default - RoverLocationsLive index, status filter, form, show, badges - Rover.Compute and rover_live (only_ideal_locations → only_good_locations) - RoverPlanning context candidate filter (status == :good) - RoverPlanning.Show / Form copy - All rover-related tests

@moduledoc """
|

A planned rover mission. Owned by a user but globally visible. Holds
|
|
the band + height parameters that drive path-profile computation, the
|
|
list of stationary endpoints (`stations`), and the matrix of computed
|
|
paths from each rover-location to each station (`paths`).
|
|
|
|
`only_known_good` toggles whether the rover endpoint set is the
|
|
`:good` rover-locations (default) or every rover-location.
