[ADD] estate: Created new module and added a link with existing module

Chapter 13: Interact With Other Modules

- Created the 'estate_account' module as a link between the 'estate' and
  'account' modules.
- Added logic to generate an invoice when a property is marked as 'Sold'.
- Overrode the 'action_sold' method in the 'estate.property' model to initiate
  the invoice creation process.
- Implemented the creation of an empty 'account.move' (invoice) with the
  necessary details (partner_id, move_type, and journal_id).
- Added functionality to include two invoice lines during the invoice creation:
  6% of the selling price and an additional 100 INR for administrative fees.
