fix: strip tag decorators from winner/loser before guild_squadron comparison

guild_squadron is the clean short name from SQUADRONS.json (e.g. DSPLA)
but winning_team_squadron in the replay is the raw tagged value (-DSPLA-).
They never matched for dash/underscore-tagged squads so bar_color was
always not_involved instead of win/loss on the guild's own scoreboard.
