Cover the second MIME value and a successful generic-video fallback.

The test covers video/mp2t only with .ts, and does not cover video/vnd.dlna.mpeg-tts. Add that case. Also add a positive .mp4 or .mov case using one of these generic video MIME values. The existing application/octet-stream case covers a different generic MIME input.

Add the Windows MPEG-TS MIME case to the existing filePreviewKind table.

video/vnd.dlna.mpeg-tts is in the generic MIME set, but the filePreview tests never exercise it. Removing that entry would make clamp.ts classify as video without a test failure. The existing attachment preview classification table can hold both MIME cases, so the standalone it should move into it.

Cover both OS-reported MIME types at the filePreviewKind boundary.

filePreviewKind can receive video/vnd.dlna.mpeg-tts for a reachable .ts attachment, but this test covers only video/mp2t. A regression for the Windows MIME value could therefore return video without failing the file-preview regression test.
