polish(webui): calendar card titles, table/header fixes, wizard and contrast

- Calendar cards without a poster now show the series title on the
  placeholder (was an anonymous gray box until hover)
- Downloader: Seeds/Peers column no longer wraps mid-word; progress
  percentage moved outside the bar where it is readable at 0%
- RSS: Refresh All icon uses NButton's icon slot (was glued to label)
- Setup wizard: progress bar counts the current step (was empty on
  step 1), animates via transform with reduced-motion fallback,
  description text raised to AA contrast
- Card titles use the primary text color — headers were lighter than
  body text (inverted hierarchy) across every card
