feat: complete all screens - client tabs, payments list, remittance detail, new ticket, installations tab

- Client detail: Subscription/Invoices/Payments tabs now fully functional
- Payments: proper list with today's total + live search prefill from client
- Record payment: debounced live search, reference required for non-cash
- Remittances: detail screen with included payments breakdown
- Tickets: status filter chips + create button, new ticket with categories
- Installations: tab now visible with list + confirm flow
- Fix: remove duplicate @react-navigation/elements causing Metro asset error
- Fix: metro.config.js asset resolution from node_modules
