Paper Dynasty discord bot: get_lineups_from_sheets reads position+card_id from Google Sheets but never validated if the player can actually play that position. Added check against player.pos_1-pos_8 fields. Also added PositionNotFoundException handling at all read_lineup call sites in cogs/gameplay.py. Error manifested as 'C ratings not found for 2024 Aaron Judge' when an outfielder was listed at Catcher.
