Mobile viewport fixes: responsive card width, nav cleanup, season percentages

- Continue Watching card uses viewport-relative width on mobile (calc(100vw-3rem))
  with edge-to-edge scroll container using negative margin trick
- Nav bar hides user name on mobile (bottom tab bar shows it instead)
- Season rows show percentage text on mobile where progress bar is hidden
- Season 5 correctly shows "94%" instead of requiring the hidden progress bar
