Issue 190: feat: Add endpoint to serve dynamic Protocol Health status

[AlAfiz]

Description

Our current /status endpoint just hardcodes a "connected" message.
To be truly production-ready, this endpoint needs to dynamically ping the PostgreSQL database and the Stellar Horizon RPC.
If the database takes longer than 2 seconds to respond, the status should downgrade from "Operational" to "Degraded".
This allows the frontend to automatically display a yellow warning banner to users if the infrastructure is struggling under Wave 3 traffic.

Requirements

• Update the /api/v1/status endpoint controller.
• Implement a Promise.race() that pings the Prisma database with a 2-second timeout.
• Implement a similar ping to the Horizon API.
• Return a detailed JSON object: { status: "degraded", databaseLatency: "2500ms", rpcLatency: "120ms" }.
