Activities not displaying in contact page – “Load more” button unresponsive (v4.1.2, self-hosted)

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.
• This issue is not already reported on Github (I've searched it).
• I agree to follow Monica's Code of Conduct.

Bug description

I can successfully add contacts and log activities for them through the contact detail page. However, the activities do not appear in the “Activities” section of the contact's page. The interface shows the "Add activity" option, and activities are saved correctly (as confirmed by the dashboard counter increasing), but: No activities are shown under the contact. The “Load more” link does not trigger any visible action. The dashboard correctly counts each new activity, which indicates that data is being stored. A screenshot is attached for reference.

Steps to reproduce

1. Install Monica v4.1.2 on a self-hosted environment.
2. Create a contact.
3. Add one or more activities to the contact from the contact’s detail page.
4. Observe the “Activities” section – nothing is displayed.
5. Click the “Load more” link – no effect.

Expected behavior

Activities should be displayed in the contact’s detail view. The “Load more” link should load older activities.
