[ADD] estate: initial module structure and estate.property model

- Added `__manifest__.py` with module metadata.
- Created the `models` directory and added `__init__.py` to register models.
- Implemented the basic `estate.property` model with fields such as:
  - name, description, postcode
  - expected_price, selling_price
  - bedrooms, living_area, facades, garage
  - garden, garden_area, garden_orientation, date_availability

This serves as the foundational structure for the Real Estate application as part of the Odoo tutorials.
