[IMP] estate: Added Controllers, Wizard and Access Security

1. Create a 'Properties' menu on the website to list available properties
   (not sold/canceled/archived) in a grid view.
   - Added property images to be displayed on the front-end.
   - Implemented pagination with a maximum of 6 properties per page.

2. Developed an 'Add Offer' wizard allowing salespersons to select multiple
   properties and submit offers in one action.
   - Wizard includes fields for price, validity, and buyer.
   - Added 'Make an offer' and 'Cancel' buttons.

3. Updated security to restrict property access and actions:
   - Added roles for Real Estate Agent and Manager with appropriate access
     rights.
   - Ensured agents can only view and manage properties within their assigned
     companies.
   - Implemented security overrides to allow agents to confirm sales without
     full invoicing access.
