Description

When no external modules are installed, the External Applications page shows two upload buttons simultaneously:

1. "Upload New Module" — top-right button (always visible)
2. "Upload First Module" — inside the empty-state card

This is redundant and confusing for administrators.

Steps to Reproduce

1. Login as Admin
2. Navigate to Settings → External Apps
3. Ensure no modules are installed (empty state)
4. Observe two separate upload buttons on the same page

Expected Behavior

When no modules are installed, only the "Upload First Module" button inside the empty-state card should be visible. The top-right "Upload New Module" button should only appear when at least one module is already installed.
