Frontend components and UX (Upload, Tokenize, Buy, Dashboard)

[RafaelJohn9]

Implement React components that map directly to the MVP flows and make the demo intuitive.

Description (deep):
Build a clean UI with a property list, property detail page, upload form, tokenize modal, buy widget, and ownership dashboard. UX must surface blockchain specifics (tx ids, tokenId, confirmations) but keep explanations simple for non-technical users. Provide loading states while waiting for Hedera transactions and clear success/error feedback. Use small animations and charts to visualize ownership.

Acceptance checklist

• Implement UploadForm, TokenizeButton, BuyForm, OwnershipDashboard
• Show Hedera tx ids and HCS event ids in UI after blockchain actions
• Add loading and confirmation states for async Hedera calls
• Implement basic client-side routing (list → detail → dashboard)
• Add a demo mode banner explaining dummy accounts are used
