Adds backend/src/intake/backgroundRemoval.ts, the shared module the drafting worker and the admin endpoints both call so a cut-out obtained either way is undoable the same way.
cutoutPathFor is pure and writes a new file beside the original rather than overwriting it, which is what keeps the original restorable and makes the JPEG-to-PNG change free. removeImageBackground only points the row at the new file after it is already on disk, and is idempotent via the original_image_path IS NOT NULL check — load-bearing twice, since it also stops a second pass from recording the cut-out as the original and losing the real one for good. restoreImageOriginal swaps the paths back and deliberately leaves the cut-out file on disk.
Extends the Task 1 integration test file with a stub sidecar bound to an ephemeral port and covers the no-op-on-repeat case plus three failure modes (500, non-image body, unreachable), asserting the row is left untouched in every failure case.

Adds the two columns the background-removal feature (#281) is built on: item_drafts.remove_background (boolean, not null, default true) records the submitter's per-submission intent, and item_images.original_image_path (nullable text, no default) records where a cut-out photo came from so it can be restored. The default on remove_background is load-bearing — any row written by a path that does not mention the column behaves like the new default, so no backfill is needed. original_image_path stays null until a photo has actually been cut out, which doubles as the answer to "can this be restored?" rather than needing a separate flag. Also updates the Drizzle mirror in src/db-drizzle/schema.ts by hand (the local dev database was not running to re-pull from) and adds the integration test backgroundRemoval.integration.test.ts, including the exported seedSubmission helper that Task 3 will reuse.
Closes#281
