fix: Conservative FMV valuations - no more inflated prices!

- Reduced base prices to realistic restoration project values
  * Griswold #8:  →  (60% reduction)
  * Wagner #8:  →  (58% reduction)
  * Lodge #8:  →  (69% reduction)
- Added condition detection:
  * Restored items: 1.5x FMV (deserves premium)
  * Damaged/cracked: 0.5x FMV (realistic discount)
- Now finding 6 real deals instead of 40+ questionable ones
- Deals are now TRULY exceptional (80%+ off realistic values)
- No more false positives from inflated FMV
