fix(mocks): use dynamic origin for MSW url (#177)

[rupeshca007]

Description

Fixes #177.

This PR resolves an issue where the Mock Service Worker (MSW) endpoints were hardcoded to http://localhost:3000. This caused mock intercept failures whenever the development server started on a different port (e.g. 3001, 3002), which often happens if port 3000 is already in use.

Changes

• Dynamic Origin Detection: Replaced the hardcoded base URL with window.location.origin in stantardGetEndpoint.
• • Protocol-Agnostic WebSockets: Updated the WebSocket API setup to dynamically determine both the protocol (ws: or wss:) and the host from the current browser environment, ensuring compatibility across different deployment scenarios.

Verification Results

This fix has been thoroughly tested locally:

• Alternative Port Simulation: Forced the development server to run on Port 3002 using $env:PORT="3002"; npm run start-with-mocks.
• • Automated Browser Audit: Verified using a real browser to ensure MSW intercepted traffic correctly on port 3002.
• • Confirmed Interception: Inspected logs to verify that MSW successfully intercepted traffic on port 3002.
• • WebSocket Validation: Verified that the mock WebSocket connection correctly initialized and handled __ping__ / __pong__ messages using the dynamic host configuration.
