Closes#90
Replace sequential awaits with asyncio.gather() in all locations identified
in the issue:
- commands/gameplay/scorebug.py: parallel team lookups in publish_scorecard
and scorebug commands; also fix missing await on async scorecard_tracker calls
- commands/league/submit_scorecard.py: parallel away/home team lookups
- tasks/live_scorebug_tracker.py: parallel team lookups inside per-scorecard
loop (compounds across multiple active games); fix missing await on
get_all_scorecards
- commands/injuries/management.py: parallel get_current_state() +
search_players() in injury_roll, injury_set_new, and injury_clear
- services/trade_builder.py: parallel per-participant roster validation in
validate_trade()
