[Vault POC] Liquidation Flow

[jrwbabylonlab]

Simulate and validate the liquidation process within the devnet environment, and ensure the UI correctly reflects a liquidated vault/position state.

Scope
1. Work with protocol/devops to simulate a liquidation event in devnet (trigger liquidation against a test vault/loan).
2. Confirm the system emits the correct events/status updates that can be consumed by the frontend.
3. Update the frontend to query and detect liquidation from the vault and position APIs.
4. Display the liquidated state in the UI with clear messaging to the depositor.

Notes
• The frontend does not initiate liquidation — only observes the resulting state.
• Simulation is required so the team can test and adjust the UI accordingly.
