Subject: [PATCH] Bug 40959: Fix LOC classification display (staff interface)

This patch fixes the display logic for the LOC classification field
(050).

The current issue is that the inner components (each subfield) gets
separated with the pipe symbol (|) instead of grouping the components
together and using the separator for the outer 050 occurences.

To test:
1. Open a record to edit it
2. Add 050 like this:

```
050  4 $aE337.5 $b.O54 2025
050  4 $aE415.7 $b.A44 2025
```

3. Save
=> FAIL On the staff interface it displays:

```
LOC classification: E337.5 | .O54 2025 E415.7 | .A44 2025
```

4. Apply this patch
5. Run:
   $ ktd --shell
  k$ restart_all
6. Reload the detail page
=> SUCCESS: Things display correctly!
7. Sign off :-D
