feat(server): use embedded preview from raw images (#8773)

* extract embedded

* update api

* add tests

* move temp file logic outside of media repo

* formatting

* revert `toSorted`

* disable by default

* clarify setting description

* wording

* wording

* update docs

* check extracted image dimensions

* test that it unlinks

* formatting
