On auth failure during pull (access + refresh both expired), sync_plugin now
fires SyncConfigureRequestEvent so the Connect modal reopens automatically
instead of leaving the player with a silent error status. The modal's existing
double-open guard keeps repeated failures idempotent.
Also removes the unused SyncAuthResultEvent (results handled inline in
SyncSetupPlugin via PendingAuthTask polling) and adds server deployment
artifacts: Dockerfile (multi-stage, SQLX_OFFLINE), docker-compose.yml (SQLite
volume, health-check), and .env.example for local development setup.
