[ADD] real_estate: initial module structure and database table

Created the initial file architecture for the real_estate module,
including the necessary directories and manifest file.

Implemented the estate.property model using Odoo ORM to
define the database table structure required for storing property-related data.

This commit sets up the foundation for the module, making it ready for
further development of features such as property management, views,
and business logic.
