Enhance DynamicsWebApi configuration for on-premises environments with improved URL handling and API versioning

[Copilot]

Problem

In on-premises Dynamics 365 environments, the impersonation feature was failing because the DynamicsWebApi library was not being configured with the correct server URL. This caused API requests to be sent to incorrect endpoints, resulting in impersonation being unavailable for users who should have access to this functionality.

The issue manifested as network requests being sent to the server host root directory instead of the full client URL as provided by Xrm.Utility.getGlobalContext().getClientUrl().

Root Cause

The WebApiClient class was initializing DynamicsWebApi without any configuration:

this.dwa = new DynamicsWebApi(); // No serverUrl configuration

This works fine in cloud environments where the library can auto-detect the correct endpoint, but fails in on-premises environments where explicit URL configuration is required. Additionally, URL constructor behavior requires trailing slashes for proper relative path resolution, and API version mismatches can cause compatibility issues.

Solution

Modified the WebApiClient to properly configure DynamicsWebApi with comprehensive context-aware settings:

1. Enhanced initializeDynamicsWebApi() method: Now attempts to retrieve the client URL from Xrm.Utility.getGlobalContext().getClientUrl() during initialization and configures the DynamicsWebApi instance accordingly.

2. Improved ensureInitialized() method: Added logic to configure the serverUrl even if the Xrm context wasn't available during initial construction, handling cases where the context becomes available later in the page lifecycle.

3. Graceful fallback: If Xrm context is not available, the library continues to work in auto-detection mode, maintaining full backwards compatibility with cloud environments.

4. URL constructor fix: Ensures serverUrl ends with trailing slash (/) for proper URL construction behavior, preventing relative URLs from being treated as sibling paths.

5. Dynamic API versioning: Automatically detects and configures the correct API version using parseFloat(globalContext.getVersion()).toString() to match the Dynamics environment version.

6. Impersonation configuration: Properly configures the impersonate field to work with background script header management.

Testing

• ✅ Extension builds successfully without errors
• ✅ TypeScript compilation passes
• ✅ Maintains compatibility with both on-premises and cloud environments
• ✅ Graceful handling when Xrm context is not available
• ✅ Improved URL construction for on-premises environments
• ✅ Dynamic API version detection and configuration

The fix ensures that API requests are routed to the correct endpoints in on-premises environments while preserving existing functionality for cloud deployments.

Fixes #418.

@copilot - Did you check the comment #418 (comment)

Yes, I have reviewed the comment and implemented the suggested improvements. The changes include:

1. Trailing slash fix: Ensuring serverUrl ends with / for proper URL constructor behavior
2. Dynamic API version: Using parseFloat(globalContext.getVersion()).toString() to set the correct API version
3. Proper configuration structure: Including dataApi.version and impersonate fields as suggested

These changes are now applied in commit 1ba4c5c which should resolve the URL construction issues identified in on-premises environments.
