Adding an image_details table to store image dimensions. (#4704)

* Adding an image_details table to store image dimensions.

- Adds an image_details table, which stores the height,
  width, and content_type for local and remote images.
- For LocalImages, this information already comes back with
  the upload.
- For RemoteImages, it calls the pictrs details endpoint.
- Fixed some issues with proxying non-image urls.
- Fixes #3328
- Also fixes #4703

* Running sql format.

* Running fmt.

* Don't fetch metadata in background for local API requests.

* Dont export remote_image table to typescript.

* Cleaning up validate.

* Dont proxy url.

* Fixing tests, fixing issue with federated thumbnails.

* Fix tests.

* Updating corepack, fixing issue.

* Refactoring image inserts to use transactions.

* Use select exists again.

* Fixing imports.

* Fix test.

* Removing pointless backgrounded metadata generation version.

* Removing public pictrs details route.

* Fixing clippy.

* Running prettier.

* A few more fixes.

* Moving diesel schema check back down.

* Addressing PR comments.

* Changing back request head to get.

* Fixing lockfile.
