Migrate to URP wizard cannot complete step 4 on a project already on URP, because the objects it counts are ones the converter will not convert

Steps to reproduce:

1. Create a project with the 2D (Built-In Render Pipeline) template in 6000.6 and close it
2. Open the project in 6000.7.0b1
3. Install the com.unity.project-auditor-rules package
4. Open "Window > Analysis > Project Auditor > Migrate to URP"
5. Tick the backup confirmation and press "Start Migration", then let steps 1 to 3 complete
6. At step 4, read "Current Render Pipeline" and "Objects to convert"
7. Press "Open Render Pipeline Converter", then press "Scan"
8. Read the "Rendering Settings" group and attempt to press "Convert Assets"
9. Return to the wizard and press "Re-analyze project"

Actual results: Step 4 reports Objects to convert: 7 and does not advance, on a project whose "Current Render Pipeline" it also reports as Universal.

The converter lists the same 7 objects, 1 Graphics "Default Render Pipeline" and 6 Quality levels, each with status — and the text "already references a Render Pipeline Asset". "Convert Assets" is disabled, nothing is selectable, and the group reports 0 warnings, 0 errors and 0 successes.

"Re-analyze project" does not clear the count. The wizard advances only via "Skip to Summary", a control labelled as abandoning the step rather than completing it.

Expected results: A project already on URP does not report outstanding conversion work. Either the rule does not fire on settings that already reference a Render Pipeline Asset, or step 4 treats "the converter has nothing left to convert" as completion and advances normally.

Reproducible with versions: 2.0.0(6000.7.0b1)

Tested on (OS): MacBook Pro - Tahoe 26.6.2
