## Why

#297 stops new encodes writing the empty `sdtp` box that iPhone Safari refuses. 26 video Releases were published before it and still have one. Justin, in #uploads-and-embeds: redo them all; a new CID is fine.

## What

`POST /enrich/repackage {"cid": ..., "dry_run": false}` (API key, like `/enrich/torrent`), in its own routes file so it doesn't collide with #290.

Inside the IPFS node, through MFS (`services/repackage.py`):
1. Find every `stream_*/init*.mp4` and remove any empty `sdtp` (the same code as #297, split into `drop_empty_sdtp_bytes`).
2. `files/cp` the release by reference, `files/write` only the fixed init segments, plus `metadata.json` with `repackaged_from: <old CID>`.
3. `files/stat` for the new CID, `pin/add` it, remove the MFS scratch copy.

Nothing is downloaded, re-added or re-encoded, so the 1.4 GB release costs about as much as a short clip. The old CID stays pinned. There's no timestamp in what's written, so the same release always gives the same new CID: running it twice pins nothing new.

## Checked

- **Against a real kubo 0.43** (a throwaway offline container on hunter), on a release built from `QmbYnW…`'s own 360p files: the new init segment is byte-identical to test 18, the one Skyler's iPhone played. Every media segment and the audio rendition keep the same blocks. Both CIDs are pinned, the MFS scratch copy is gone, and a second run gives the same CID.
- That run caught a bug the first fake didn't: kubo reads a `/` in the multipart filename as a directory. Fixed, and the test's fake kubo now refuses it the same way.
- 149 delivery-kid tests pass (5 new in `tests/test_repackage.py`). The endpoint answers 401 without a key. Merges cleanly with #290.
- Not checked: on delivery-kid itself.

## After deploy

1. With the API key, dry run first, then for real:
   ```
   for c in $(cat sdtp26.txt); do curl -s -X POST https://delivery-kid.cryptograss.live/enrich/repackage -H "X-API-Key: $KEY" -H 'Content-Type: application/json' -d "{\"cid\":\"$c\",\"dry_run\":true}"; echo; done
   ```
2. Move each `Release:<old>` to `Release:<new>`, keeping its history; the old title redirects. 24 of them have a `bittorrent_infohash` for the old bytes. That field has to go, so the Blue Railroad job makes a torrent of the new ones.
3. Unpin the old CIDs once the pages have moved.

The 26 (every Release whose video init segment has the box; the other 18 video Releases have none):
