[ADD] real_estate: added inheritance in the module

This commit extends the Real Estate module by incorporating three types of
inheritance:

Python inheritance: Applied Python inheritance to streamline code
structure, promoting reusability and maintainability.

Model inheritance: Utilized Odoo's model inheritance features to extend existing
models, adding new fields and behaviors while preserving core functionalities.

View inheritance: Employed view inheritance to customize and enrich user
interfaces, ensuring seamless integration with existing elements.
