Honest pricing review with disclaimers

What Changed:
- Added VERIFIED-PRICES.md with honest assessment
- Added BUDGET-REALITY.md explaining challenges
- Added disclaimers to all option files
- Clearly marked estimates vs verified data

Key Findings:
- Could NOT get live quotes due to cookie popups
- £2,000 budget is VERY TIGHT for July/Aug peak
- Realistic Eurocamp: £1,500-2,500 for 14 nights
- Brittany Ferries: £850-1,100 return with cabin

Verified Data:
- Siblu Kerlann: €250/week (June OFF-PEAK)
- Eurotunnel: £250-400 return avg
- Budgeting Mum: £600/10 nights OFF-PEAK

User action needed:
- Manually check Eurocamp.co.uk
- Consider shorter duration
- Consider gîte instead of mobile home
