[ADD] estate: introduce Kanban view for properties

Add a new Kanban view to visually display properties with a
custom layout powered by QWeb templates. This improves user
experience compared to the traditional list view by providing
a card-like structure.

The Kanban view includes:
 - property name and key pricing details
 - expected price and tags always visible
 - best price shown only when offers are received
 - selling price shown only when an offer is accepted

Additionally:
 - properties are grouped by type by default
 - drag-and-drop reordering is disabled to preserve consistency

This change makes property browsing more visual and intuitive,
while respecting Odoo’s guidelines for modular and customizable
UI components.
