project_panel: Fix alignment of folded directory path components (#47648)

Smit Barmase created 

The padding on folded directory path components was causing the first
component to be misaligned with regular entry labels. This adds a
negative margin to the first component to compensate for the left
padding while preserving the hover background.

Before:
<img height="180" alt="before-1"

src="https://github.com/user-attachments/assets/1825e12b-eb55-48fe-9b3c-ac52e552581b"
/>

After:
<img height="180" alt="after-1"
src="https://github.com/user-attachments/assets/03b1029d-6664-49bd-9371-680fc912c67c"
