Display bar chart labels inside bars with adaptive text color

Move game/type labels from a fixed-width column into the bar itself so
long names like "Pokemon Brilliant Diamond" aren't truncated. Compute
luminance from the bar's hex color to pick dark or light text, with a
subtle text shadow for readability at bar/track boundaries.
