[BUG] "SAFETY BLOCK" error when processing files located in the Library Root

[preikschat]

What happened?

The Library Manager correctly identifies "loose" audio files in the root of a configured library (R:\organized_library), but fails to apply the fix.

The background worker generates a warning that the book path is "not under any configured library" and incorrectly "guesses" a parent UNC path (\10.148.58.50\Audio_RW_Curated) as the library root. When attempting to apply the fix, a SAFETY BLOCK error occurs because the application believes the new destination is outside of the authorized library boundaries.

Expected behavior

The application should recognize that files in the root of R:\organized_library are already within a configured library. When applying a fix, it should move/rename them into subfolders (based on the naming template) within that same library path without triggering a safety block.

Steps to reproduce

Map a network drive (e.g., R:) to a network share.

1. Configure a Library Path in Settings as R:\organized_library.
2. Place audio files directly into the root of R:\organized_library (not in subfolders).
3. Run a Deep Library Scan.
4. Navigate to Pending Fixes and click Apply All or the checkmark for a specific book.
5. Observe the browser popup error: SAFETY BLOCK: Path outside library!.

Environment

• Version: v0.9.0-beta.134
• Platform: Windows / Bare metal (running via venv/python)
