Test Fixes for fetch-mock v12

The upgrade to fetch-mock v12 introduced several breaking changes that required test modifications:

1. Custom Jest Environment

Added tests/jest-environment.js to expose Node.js built-in fetch globals (Request, Response, ReadableStream, Headers) that fetch-mock v12 expects to be available.

2. API Changes

• fetchMock.mock() → fetchMock.route()
• fetchMock.once() → fetchMock.route(..., { repeat: 1 })
• fetchMock.reset() → fetchMock.removeRoutes().clearHistory()
• fetchMock.called() → fetchMock.callHistory.called()
• fetchMock.calls() → fetchMock.callHistory.calls()

3. Removed Deprecated Features

• Removed fetchMock.config.overwriteRoutes = true (no longer needed)
• Removed const { Response } = fetchMock.config (Response now comes from globals)

4. Route Management

• Added explicit route names using the third parameter for better control
• Updated mock initialization to use fetchMock.removeRoutes().clearHistory().mockGlobal()
