Add admin_processing_issues_templ.go template for managing processing issues
in the admin dashboard. This template provides:
- List view of all processing issues with filtering by severity
- Issue details display (file path, error type, description)
- Actions to resolve or dismiss issues
- Integration with the ProcessingIssuesHandler API endpoints
This UI enables administrators to monitor and address processing errors that
occur during media scanning and import workflows.
