Summary

A video and a picture with the same name are not necessarily halves of the same live photo.
Resolve the poster through the DAV live photo metadata when the video carries it, and keep the
name pairing only for videos without metadata. A picture that already belongs to another live
photo is not used as a poster by name.

This makes video poster resolution symmetric with the image path, which already uses metadata.

How to test

1. Upload a live photo pair where the still and the video have different names.
2. Open the video in the viewer.
3. The poster should be the correct still frame resolved via metadata-files-live-photo.
4. Rename the still; the poster remains correct.

Unit tests added in __tests__/component/media.spec.ts and __tests__/utils.spec.ts.

@bulungasdeveloper thanks for the PR!

@artonge what do you think of that ? You have more knowledge than me on live photos metadata :))
