[ADD] estate : extend CRUD operations and add property view under user

. Restrict deletion of properties unless their state is New or Cancelled
. Automatically update property state to Offer Received when a new offer is created
. Prevent creation of offers lower than existing highest offer
. Display salesperson’s available properties directly on the user form
. Introduce a new tab in user settings to manage linked properties
