Build out the Emergency Transfer page (app/emergency-transfer/page.tsx) beyond the placeholder with a confirm-guarded flow

[Menjay7]

Summary

Replace the placeholder implementation of app/emergency-transfer/page.tsx with a fully functional Emergency Transfer experience featuring a confirmation-guarded workflow.

This PR introduces a dedicated transfer flow designed for high-risk and irreversible operations, ensuring users explicitly review and confirm actions before submission.

Problem

The current Emergency Transfer page is only a placeholder:

No functional transfer workflow exists.
Users cannot review transfer details before execution.
High-risk actions lack confirmation safeguards.
There is no validation, error handling, or feedback mechanism.
The page is not ready for production use.
Solution

Implement a complete Emergency Transfer interface with a multi-step, confirmation-driven experience.

Features
Transfer Form

Collect required transfer information:

Destination account/address
Asset or token selection
Transfer amount
Optional notes or reason for transfer
Emergency Transfer
├── Destination
├── Asset
├── Amount
└── Notes (Optional)
Validation

Validate inputs before allowing submission:

Required fields present
Valid destination format
Positive transfer amounts
Available balance checks
Asset-specific constraints
Confirmation Guard

Before execution, present a confirmation screen summarizing the operation:

Review Emergency Transfer

Destination: GABC...XYZ
Asset: USDC
Amount: 1,000

merged the emergency-transfer page (confirm-guarded flow) - dropped a stray lowercase dashboard-widget copy from the branch that collided with the canonical components/Dashboard one, so just the page landed. good work @Menjay7 👍
