Persist live status and migrate legacy live data

- Add user_live_status to store hi score, hi combo count, and clear count per chart
- Expand user_live_goal to persist achieved live_goal_reward_id entries instead of only coarse goal types
- Update live reward handling to refresh live status and sync newly achieved live goals on every clear
- Return live status and achieved goal ids from stored user data in /api/live/status
- Aggregate profile liveCnt from stored user_live_status instead of hardcoded values
- Load complete-rank thresholds from live info for goal evaluation
- Migrate legacy user_live_record data into user_live_status and backfill achievable live goals on startup
