fix(dashboard): preserve DB data across log parser restarts

Browse Source 
Changed _init_db() from DROP+CREATE to CREATE IF NOT EXISTS so that
trade history, candle data, and daily PnL survive container restarts.
Previously all tables were dropped on every parser start, losing
historical data if log files had been rotated.
