Handle unlinked high-res proxy blocks with fallback lookup

When proxyLinks is empty (no explicit .gves→hires linkage), now also process unlinked high-res proxy blocks that have:
- IsProxy: true
- FilePath: null
- Title metadata (e.g. 'File 1', 'File 2')

Uses fallback lookup to find matching files in hiresMediaFolder by Title, then injects FilePath into the XML Media block. This handles the case where FramelightX creates proxies but doesn't establish explicit linkages.
