Improve high-res file matching: use substring search instead of exact title match

When searching for high-res files by Title metadata, now looks for files that CONTAIN the Title rather than requiring exact match. This handles cases like:
- Title: 'File 1' → matches 'ZacIsCool--File 1.mp4'
- Title: 'File 2' → matches 'ZacIsCool--File 2.mp4'

Makes the fallback lookup more flexible and practical for real-world filename patterns.
