test(lidarr): extract and cover the track row style branch

The snapshot harness renders to a plain string, so colour and text modifiers never reach the assertion. The track row's downloaded and missing arms were therefore invisible to the suite: swapping either arm for the other, or inverting the has_file condition, all left the full run green.

Move the branch into decorate_track_row_with_style, mirroring the row decorators already extracted in the other library detail views, and unit test both arms directly against Row equality. All three mutations now fail the suite.
