change processing filter selection and editing behavior

[hamed-musallam]

• New Filter:
  This functionality is working well as is, and no changes are needed to the current behavior.

• Existing Filter:

1. Click on the filter tool from the main toolbar:
   When we click on the tool, it re-applies the filters up to the selected filter, displaying all related sub-tools. The selected filter is marked as active in the processing panel (highlighted in green), and the filter's options are opened in both the processing panel and the header.

2. Click on the "Restore filter" button:
   This triggers the same behavior as clicking on the tool—reapplying the filters and making the selected one active with its options visible.

3. Click on a filter in the processing panel:
   Clicking on a section will open or close it for viewing, but editing will not be allowed within the section.
