Redirect DAISY pages to Archive item pages

[nathanpixodeo]

Refs #9439

Fixes the stale /books/.../daisy flow by redirecting editions with an ocaid to their Internet Archive item page instead of rendering the old page with a guessed _daisy.zip download URL.

Technical

• Adds a redirect from the DAISY route to https://archive.org/details/{ocaid} when an edition has an Archive identifier.
• URL-escapes the Archive identifier path segment before redirecting.
• Keeps the existing no-ocaid fallback page behavior.

Testing

• python -m py_compile openlibrary/plugins/upstream/addbook.py openlibrary/plugins/upstream/tests/test_addbook.py
• python -m ruff check openlibrary/plugins/upstream/addbook.py openlibrary/plugins/upstream/tests/test_addbook.py
• Attempted targeted pytest locally, but this machine only has Python 3.13 while Open Library requires Python 3.14; pytest import fails under 3.13 before reaching this test because annotations in openlibrary/core/helpers.py are evaluated differently.

Screenshot

Not applicable; this is a redirect behavior change.
