feat: add opt-in verbose mode for capturing HTTP response metadata

Add verbose mode to DescopeClient and HTTPClient to capture HTTP response
metadata (headers, status codes, etc.) for debugging failed requests.

Key changes:
- Add DescopeResponse wrapper class providing dict-like interface while
  exposing HTTP metadata (headers, status_code, text, etc.)
- Add verbose parameter to DescopeClient and HTTPClient (defaults to False)
- Add get_last_response() methods to access captured response data
- Maintain full backward compatibility (zero overhead when disabled)
- Add comprehensive tests (366 total tests passing)
- Add usage examples and documentation

This enables customers to capture cf-ray headers and other HTTP metadata
when troubleshooting issues with Descope support.

Fixes descope/etc#12957

+### Verbose Mode for Debugging
+
+When debugging failed API requests, you can enable verbose mode to capture HTTP response metadata like headers (`cf-ray`, `x-request-id`), status codes, and raw response bodies. This is especially useful when working with Descope support to troubleshoot issues.
+
+```python
+from descope import DescopeClient, AuthException
+import logging
+
+logger = logging.getLogger(__name__)
+
+# Enable verbose mode during client initialization
+client = DescopeClient(
+    project_id="<Project ID>",
+    management_key="<Management Key>",
+    verbose=True  # Enable response metadata capture
+)
+
+try:
+    # Make any API call
+    client.mgmt.user.create(
+        login_id="[email protected]",
+        email="[email protected]"
+    )
+except AuthException as e:
+    # Access the last response metadata for debugging
+    response = client.get_last_response()
+    if response:
+        logger.error(f"Request failed with status {response.status_code}")
+        logger.error(f"cf-ray: {response.headers.get('cf-ray')}")
+        logger.error(f"x-request-id: {response.headers.get('x-request-id')}")
+        logger.error(f"Response body: {response.text}")
+
+        # Provide cf-ray to Descope support for debugging
+        print(f"Please provide this cf-ray to support: {response.headers.get('cf-ray')}")
+```
+
+**Important Notes:**
+- Verbose mode is **disabled by default** (no performance impact when not needed)
+- When enabled, only the **most recent** HTTP response is stored
+- `get_last_response()` returns `None` when verbose mode is disabled
+- The response object provides dict-like access to JSON data while also exposing HTTP metadata
+
+**Available metadata on response objects:**
+- `response.headers` - HTTP response headers (dict-like object)
+- `response.status_code` - HTTP status code (int)
+- `response.text` - Raw response body as text (str)
+- `response.url` - Request URL (str)
+- `response.ok` - Whether status code is < 400 (bool)
+- `response.json()` - Parsed JSON response (dict/list)
+- `response["key"]` - Dict-like access to JSON data (for backward compatibility)
+
+For a complete example, see [samples/verbose_mode_example.py](https://github.com/descope/python-sdk/blob/main/samples/verbose_mode_example.py).
