Add square footage field to property Details page

Problem statement:

• There's no dedicated field to view or enter a property's square footage in Hospitable
• This information is important for property management, listing accuracy, and guest communications

Current workaround:

• No built-in workaround — property managers either track this externally or omit it entirely

Impact:

• Inconsistent property information across platforms
• Extra manual effort to track square footage outside Hospitable
• Potential for errors when sharing property details with guests or on listing sites

Proposed solution:

• Add a "square footage" field to the property Details page (Essentials section)
• Make it visible and editable for property managers

Unlock:

• Property managers can accurately display square footage directly in Hospitable
• Streamlined property data management without relying on external tracking
