feat(dashboard): NiceGUI Genomes page con top-K + ispezione singolo genoma

Aggiunta route /genomes:
- Run selector + Top K (10/25/50)
- Tabella sortable con fitness, DSR, Sharpe, max DD, trades, style, T, lookback
- Selezione riga → pannello ispezione con 6 metric card e blocchi code per
  system_prompt + raw_text + parse_error eventuale
- Auto-refresh ogni 3s (mantiene selezione corrente se ancora valida)
- Header nav aggiornato con link Genomes
