Subject: [PATCH] refactor(tasks): extract filename regex to shared constant

Move the valid filename regex pattern to a shared constant in `app/utils/filename_utils.py` and update both the task logic and security tests to use it. This eliminates duplication and ensures consistency across the codebase.

Normalized line endings in `app/tasks/extract_metadata_with_gpt.py` from CRLF to LF to ensure consistency and prevent CI issues.
