fix: Improve price extraction to avoid fantasy prices on Dashboard

- Added more price selectors (data-testid, price-current, prix-actuel, etc.)
- Added validation to reject unreasonable prices:
  * Reject if <= 0 or < 0.01€ (errors)
  * Reject if > 100,000€ (wrong element)
- Better strikethrough detection to skip old prices
- More detailed logging with price values

Fixes Dashboard showing incorrect/fantasy prices
