Fix Select trigger display values and add TMDB attribution

Base UI Select.Value renders raw values by default — add children render
functions to map values to human-readable labels (e.g. "this_month" →
"This Month", "0" → "unlimited"). Switch inline select underlines from
border-bottom to text-decoration for proper baseline alignment. Add TMDB
attribution with logo and disclaimer to settings footer.
