[IMP] real_estate: Added model relations, computed fields and action buttons

- Linked models using One2many, Many2one, and Many2many fields
- Added computed fields like best_offer and offer_deadline
- Implemented onchange methods for dynamic field updates
- Created type='object' buttons:
  • Sold / Cancelled on properties
  • Accept / Refuse on offers
