FIX / Remove deprecated /public prefix from plugin URLs

[Mary-Clb]

• I have performed a self-review of my code.
• I have added tests (when available) that prove my fix is effective or that my feature works.
• I have updated the CHANGELOG with a short functional description of the fix or new feature.
• This change requires a documentation update.

Description

• The plugin still built 6 URLs with the deprecated /public path, which broke the tree view page. This fix removes them.
