fix(author): sanitize output filenames at job creation time

Added explicit sanitization of output paths when creating authoring jobs
to ensure special characters are removed before any filesystem operations.

The sanitization now happens in two places:
1. addAuthorToQueue: Sanitizes the output path for regular authoring jobs
2. addAuthorVideoTSToQueue: Sanitizes the output path for VIDEO_TS->ISO jobs

This ensures that:
- OutputFile field in Job struct never contains special characters
- Log filenames are sanitized (using the OutputFile basename)
- All filesystem operations use clean filenames

Before: /path/ifuckedmybestfriend'sgirlfriend.iso
After:  /path/ifuckedmybestfriendsgirlfriend.iso

The display title shown to users still contains the original text,
but all actual file operations use sanitized names.
