Windows Long Filename Signature Fix

Version: 4.37.0 Date: 2026-07-15

Goal: Fix Could not create Signature on Windows when file paths resolve to 8.3 short names (PI3CD7~1.PDF).

Solution: fs.realpathSync before hashing to get the full path; fallback to original path on failure; propagate root cause via IPBError.

Files Modified:

• src/services/fileProtect/workCopy.pipe.ts - Real path resolution before stream read
