[ADD] estate: create module with database, fields, security and views

[kuay-odoo]

This commit introduces the estate module and creation of database. We create tables and fields to manage property details, such as property name, description, expected price, and selling price. It also integrates security access rules, adding an ir.model.access.csv file that grants the base.group_user group the appropriate permissions to read, write ,create, and delete property records. These security configurations ensure that only authorized users can interact with estate data, enhancing control over data access and modification within the system.

This commit also includes the creation of menus for easy navigation of estate records, a reserved field to manage the status of properties, and the implementation of list and form views for better representation of estate data. The search view has also been configured, allowing users to filter on state value be new or offer received and group by using postcode field
