Prevent popup widget from wrapping to next line (#7673)

#### Rationale
Protein name display looks better when the popup widget isn't wrapped to
the next line in a table cell.

#### Changes
- Inject a non-breaking space to ensure no inopportune wrapping

#### Tasks 📍
- [x] Claude Code Review
- [x] Manual Testing @labkey-tchad 
  - Create a Panorama folder (subtype: Experiment)
- Import MRMer.zip
(https://github.com/LabKey/targetedms/blob/develop/test/sampledata/TargetedMS/MRMer.zip)
  - Click the Peptide Groups link in the runs grid
- Check that the protein name and down-arrow render without wrapping
       - [x] Verify Safari
       - [x] Verify Firefox
       - [x] Verify Chrome  
- ~Test Automation~
