fix: add .json suffix to check-ins route

[Jah-yee]

Summary

Frontend POSTs to /works/OL{work_id}W/check-ins.json but FastAPI route only defined for /works/OL{work_id}W/check-ins causing 404.

Fix

Added .json suffix to FastAPI router decorator.

Testing

• Check-in submission on book pages returns 200 instead of 404

Closes #12391

Pull request overview

Fixes a 404 when submitting reading-log check-ins by aligning the FastAPI POST route with the frontend’s .json URL.

Changes:

• Updated the FastAPI check-ins POST route to use /works/OL{work_id}W/check-ins.json.

[Copilot]

Changing the route from /works/OL{work_id}W/check-ins to only /works/OL{work_id}W/check-ins.json will break existing callers that still POST to the non-suffixed path (e.g. openlibrary/plugins/openlibrary/js/goodreads_import.js posts to ${work.key}/check-ins). To avoid a regression, keep the original route as an alias (e.g. add a second @router.post("/works/OL{work_id}W/check-ins", include_in_schema=False) decorator above this handler, similar to openlibrary/fastapi/books.py:42-44).

Suggested change

	@router.post("/works/OL{work_id}W/check-ins", include_in_schema=False)
