feat: add quote and transaction detail subpages

[TaprootFreak]

Summary

• Clicking a quote/transaction row now opens a dedicated detail page (/realunit/quotes/:id, /realunit/transactions/:id) instead of navigating to the user account page
• Detail pages display all available fields as key/value tables with clickable user address linking to the user account page
• Added routes and lazy imports for both new detail screens

Test plan

• Click a quote entry → navigates to quote detail page showing Type, Status, Amount, Estimated Amount, User, Created
• Click a transaction entry → navigates to transaction detail page showing Type, Amount CHF, Assets, User, Date
• Back button works on both detail pages
• User address on detail pages is clickable and navigates to the user account page
• "More" button on overview page still navigates to the full list pages
