Created the Escrow dashboard according to issues description

[KAMALDEEN333]

Built the main dashboard view displaying all escrows associated with the connected wallet, with filtering, sorting, and status-based categorization.

Requirements and Context were achieved
Background:
Users need a centralized view to manage all their escrow agreements
Dashboard serves as the primary navigation hub after login
Quick status visibility enables timely actions

Problem:
Users have no way to view their existing escrows
No visibility into pending actions required from user
Cannot track escrow lifecycle without individual lookups

Success Criteria was achieved
Dashboard page at /dashboard
Tabs/filters: All, Active, Pending Confirmation, Completed, Disputed
Escrow cards showing: title, amount, counterparty, status, deadline
Sort by: date created, amount, deadline
Search by title or counterparty address
Empty states for each category
Quick actions: View Details, Confirm, Dispute (context-aware)
Pagination or infinite scroll for large lists
Real-time status updates (polling or WebSocket)

Impact:
Central hub for all escrow management
Improves user efficiency and engagement
Reduces support requests about escrow status
