ddidderr aeec7a0345 test: cover chunk validation edge cases
Add focused regression coverage for validation rules called out in PLAN.md.
Chunk upload tests now prove that an otherwise valid upload rejects an
out-of-range chunk index through the HTTP API. Completion tests now prove that a
manually corrupted chunk file is not assembled into a final file.

Update TESTS.md so the reusable checklist reflects these automated proofs.

Test Plan:
- just check
- just nginx-smoke

# Test Scenarios
Keep this file as the reusable verification checklist while implementing
`PLAN.md`.
## Automated
- `just check`
- Runs formatting, all Rust tests, and clippy.
- Current coverage:
- `GET /` serves the static browser page.
- `GET /healthz` reports `ok`.
- `POST /api/uploads` creates `meta.json` and chunk directories.
- `POST /api/uploads` rejects an empty file name.
- `PUT /api/uploads/:id/chunks/:index` stores validated chunk files.
- `PUT /api/uploads/:id/chunks/:index` rejects wrong-size chunks.
- `PUT /api/uploads/:id/chunks/:index` rejects out-of-range indexes.
- `PUT /api/uploads/:id/chunks/:index` accepts duplicate chunks.
- `GET /api/uploads/:id` reports completed chunks from disk.
- `POST /api/uploads/:id/complete` assembles verified chunks.
- `POST /api/uploads/:id/complete` rejects incomplete uploads.
- `POST /api/uploads/:id/complete` rejects corrupt chunk files.
- `static/app.js` passes `node --check`.
- `just nginx-smoke`
- Runs upl behind nginx in Docker.
- Uploads a 17 MiB file through nginx.
- Restarts the Rust backend mid-upload, resumes through nginx, completes, and
compares SHA-256 hashes.
## Manual
These scenarios come from `PLAN.md` and should be retested as the matching
features land.
- Upload a small file in one pass.
- Upload a file larger than one chunk.
- Kill the browser tab mid-upload and resume.
- Restart the Rust server mid-upload and resume.
- Interrupt the network and resume.
- Pause from the browser controls and resume.
- Reload the page and resume from the pending upload list.
- In a browser with the File System Access API, resume without reselecting the
file after granting read permission.
- In a browser without the File System Access API, resume after reselecting the
same file.
- Retry a duplicate chunk and confirm it is accepted idempotently.
- Attempt an invalid chunk index and confirm it is rejected.
- Attempt a wrong-size non-final chunk and confirm it is rejected.
- Complete an upload and compare the final file with the source file:
- Install `deploy/nginx/upl.conf.example` on the deployment host, add the real
TLS certificate and access-control settings, and repeat the resume scenarios
through the public nginx URL.
```sh
sha256sum source-file data/complete/uploaded-file
