fix NoPayStation PSP parsing + detail-panel UnboundLocalError

- PSP_GAMES.tsv and PSX_GAMES.tsv use different headers (PSP adds Type/RAP
  columns, PSX adds Original Name). Parse the header row and map columns by
  name instead of hardcoding positions — PSP names were showing as 'Minis'/
  'PC Engine' (the Type column) with broken download URLs.
- GameDetailsPanel.set_item referenced is_ps1 before it was assigned, raising
  UnboundLocalError and leaving the detail panel stale.
