Describe the bug
When an administrator uses the Admin UI to send "Send Password Instructions" to a user (whose authentication is handled via OIDC), the email is delivered successfully, but the Admin UI shows no feedback (no success notice, no error message). Such a feedback ("email sent successfully") was shown in former versions 2.X
Expected Behavior
The Admin UI should display a success (or error) notification after the reset password email is sent, regardless of the user's authentication provider.
Current Behavior
No UI feedback is shown. The email is sent, though. The application log reveals that the email is delivered, but a Net::ReadTimeout exception is raised immediately after, causing the API response to fail before it can return a status to the frontend.

| Net::ReadTimeout (Net::ReadTimeout with #<TCPSocket:(closed)>):
| app/api/chemotion/admin_user_api.rb:168:in `block (4 levels) in <class:AdminUserAPI>'
Analysis / suspected cause [With help of Claude Sonnet 4.6]
The timeout occurs at admin_user_api.rb:168, after the mail is already delivered. This suggests that line 168 makes an outbound network call (possibly to the OIDC provider or another external service) that times out. Because this raises an unhandled exception, the API never returns a success response to the frontend, leaving the UI without any feedback. The email delivery itself works correctly, this is purely a backend exception causing a missing UI response.
Steps to Reproduce
Please provide detailed steps for reproducing the issue.
- Log in as an administrator.
- Navigate to the Admin panel → Users.
- Select a user that is authenticated via OIDC.
- Click "Send reset password instructions".
- Observe: the email is delivered, but no feedback appears in the UI.

- Chemotion CLI version: 0.2.27
- Deployment OS: Debian (in a VM), deployed via Chemotion CLI
