Expected Behavior

When clicking "Microsoft OneDrive (personal)" in the attachment menu, a Microsoft login popup should open successfully. According to the documentation, the redirect_uri sent to Microsoft should be the base URL of the Open WebUI instance (e.g., https://your-openwebui-domain.com), which is also what needs to be registered as a SPA Redirect URI in the Azure App Registration.

Actual Behavior

The popup opens but immediately fails with:

invalid_request: The provided value for the input parameter 'redirect_uri' is not valid.

Inspecting the actual URL being called reveals that Open WebUI sends the current chat URL including a dynamic chat ID as the redirect_uri:
https://your-openwebui-domain.com/c/59db652a-170f-4fa2-8cb7-679a64588dfb

Steps to Reproduce

1. Create a Personal Azure App Registration configured for consumers (Multitenant + personal Microsoft accounts)
2. Set Redirect URI as SPA: https://your-openwebui-domain.com
3. Enable Access tokens + ID tokens
4. Set the following environment variables:

ENABLE_ONEDRIVE_INTEGRATION=true
ENABLE_ONEDRIVE_PERSONAL=true
ENABLE_ONEDRIVE_BUSINESS=false
ONEDRIVE_CLIENT_ID_PERSONAL=<your-client-id>

5. Enable OneDrive toggle in Settings → Admin → Documents
6. Click "Microsoft OneDrive (personal)" in the attachment menu
7. Observe the popup failing with invalid_request
