ramseshk 6c1fb46e8a Fix auction: realistic valuations, multi-strategy comparison, role chips rendering
- Realistic price model: scales by FVM (Lautaro FVM=370 → ~199 cr, QI×5.7)
  Formula: qi * max(1.2, fvm/65) with forward premium and small-sample penalty
- 5 strategy engines: Balanced, Value, Stars, Safe, MILP-Lite
  Each with different score functions (value ratio, stability, risk adj)
- Strategy comparison radar grid: total FV, efficiency, stars, avg games, budget%
- Squad table with color-coded price bands (gold >100cr, sky >50cr, green <50cr)
- Market distribution histogram by role
- Top value picks section with cr/FV efficiency
- Fixed role_chip HTML rendering in all pages (unsafe_allow_html=True)
- Verified: 0 errors, 31 role chips, 5 KPIs, 8 charts
