This PR addresses FileUriExposedException when opening local upload items by switching from file:// URIs to content:// URIs via FileProvider.

Changes:

• Use FileProvider.getUriForFile(...) and grant read permission when launching ACTION_VIEW.
• Refactor upload-item click handling to exit early when the local file exists.
• Centralize unknown MIME-type fallback to */*.
